ITG CAI Review (For Leon Cupra Mk2) **NOW WITH VIDEO FOOTAGE**

[robjnr]

I see, Is there anyway i can tell that it is the revised one by just looking at it? Or would you have to take it apart to tell?

Anyway i'm really liking the look of this ITG filter, it certainly looks like it has the flow capacity

Physically they look the same, the only sure way of telling is if the casing says its made in Japan it is a new one, or if you can see this on the casing:

THE PART NUMBER OF THE LATEST REVISION DV IS MADE IN JAPAN PART NO: 06H-145-710-D

THE PART NUMBER OF THE EARLIER VERSION DV IS MADE IN GERMANY PART NO: 06F-145-710-C

 

[robjnr]

mine says made in Germany and starts with 06E

might be worth whipping it off and checking it. I have done a guide of sorts here. Click through each of the photos and read the text at the bottom of the photos for guidance.

 

[robjnr]

My bad i think i was looking at the wrong thing! Can't seem to find a part number on the DV will have a proper look 2morrow

Excellent review, Warren!

I don't understand why you don't seem to like aftermarket performance exhaust though.

I have a carbonfibre bonnet (exterior is painted) and wonder how important the seal of that foam wall is at the top. I think I'd have to ask ITG.

I'm also wondering if there would be any additional advantage to ducting to the ITG filter area from the 'fog' panel at low level - Something which I could easily do on my particular car.

So, you don't get any fuel cuts and need an APR fuel pump?

 

[RedRobin]

I'm certainly interested, I was some what disappointed with the Dbilas as the car was certainly not running right with it on and I have since gone back to the stock airbox arrangement to stop misfires and generally ropey running.

ITG seems to produce the only CAI to my knowledge where the design claims to take account for the MAF readings being incorrect. I'm not really fussed by the aesthetics as long as it works and doesn't make the car run bad.

....Just a thought but could your Dbilas problem be because you are running an oem fuel pump? (if indeed that is the case).

Nope running an APR fuel pump.

Not an uncommon issue having read some of the reports from our american cousins regarding aftermarket intakes, problems with the MAF scaling. Maybe software related, though APR don't appear to subscribe to that theory.

It certainly runs better now it's back on the stock air box. But would like to try out another solution in due course.

....Then it possibly supports ITG's claim that their new offering truly is the only intake which takes proper consideration of the MAF.

[I think I'm right in saying that but please correct me if wrong]

 

[ZBOYD]

Maybe, ITG seems to have a product that has been tested in that regard.

Its not that he doesnt like the aftermarket exhaust , its just he sees the exhaust as a serviceable item which he would upgrade when it blew or needed changing,
The map he has got seems fine on his standard exhaust , and he has had after market exhausts and for the money to bhp figures they give he doesnt consider it a worthwhile thing to do.

I am sure Warren will be along to comment

Mark , what sort of problems did you have?
I noticed that from rolling road results your car seems a little lower than comparison cars?
or was that sorted out and un related?

Pleased to help out
and my thinking is along the same lines mate.

....I don't want to start a debate about aftermarket exhausts and I respect your opinions.

Suffice it to say that I think there are many advantages to an aftermarket performance exhaust such as by Milltek as they are developed to exploit and be exploited by remaps by the established reputable tuners. That's quite apart from the glorious sounds they make (which may not be your thing).

Additionally, they are a component which work hand-in-hand with high flow air intakes (such as the ITG).

Millteks are performance components rather than stock consumables.

But each to their own.

 

[Carr20vt]

I was really dubious esspecially with the cost but the dp is one of the best mods imo.

The Milltek full system (cat back + race cats 100 cell) I had on my LCR really delivered very little in my eyes when I went stage 2. I can't dispute the build exceeds OEM but then at that price it should. Once I'd done the full system it turned out to be the DP that was restrictive, so you just end up going after the next weakest link.

However, read around on forums and you'll see there have been some failures creeping in recently since the volumes have gone up. Yes they get replaced under warranty, but at these kind of prices I wouldn't expect to see failure that often.

I do agree I will benefit from a DP and cat removal (once the old system fails), but until then I really don't believe they offer a good £/bhp return against some other modifications.

I'll be exploring alternative avenues to Milltek this time, not because I think their product is less than good, I'm just tired of hearing folk putting them on a pedestal as though they are the only manufacturer out there making decent exhausts. I may choose to eat my words, but nothing ventured nothing gained. Whilst I enjoy to mod, it's something you do for love, not profit or return. These days I'm taking a far more ruthless approach to it and trying to moderate where I invest without compromising overall quality.

^^^^
Well, I'm not going to try and persuade you to buy a Milltek but pro rata to their output I don't think failures of their products are any worse than anyone else's. Also, their aftersales service concerning problems is second to none in my direct experience over the last 4 years.

What I do think is unfair is how reputations can be soiled just by bods on car forums. Usually when you delve deeper into individual cases you find that there are other factors which have absolutely nothing to do with the quality of the product - It can't be helped though.

Personally I never look at mods from a value-for-money basis but prefer to consider what something contributes to the whole package.

But life would be dull if we felt the same and I trust you won't read this as a conflict - We will agree wholeheartedly on some subjects and absolutely not agree on other subjects.

Back on the topic of the ITG offering, it's looking very exciting and I'm confident that the final production version will be a good one.

I'm all good with that

Personally I never look at mods from a value-for-money basis but prefer to consider what something contributes to the whole package.

I used to be the same, and would never consider going for anything other than 'the best'. I purchased an MTM remap on this car originally at a grand. You'd think with Roland Mayer having worked for Quattro for 25 years the product would be fantastic. However I'm now running Revo stage 2, and not because I wanted a stage 2 solution or to have to invest in another map, but because it turned out to be a so-so product. Revo is not cheap, but then it's not the most expensive. However it's merits of performance surpass that of a map costing much more.

Take my KMD fuel pump. Probably the cheapest solution to getting into HPFP, and less than half the price of the APR pump after fitting. This is one area I have taken a punt on something that is cheaper and the car (from Revo's perspective) runs as well as any of the cars using other aftermarket HPFP's.

I never knowingly compromise on quality per say, but have made decisions not to be held to ransome on 'spec lists' or 'recommended supporting mods lists' unless it is going to be knowingly detrimental to the cars welfare. Whilst I'll concede my DP and cats probably aren't loving life right now, and occasionally they get worked hard, I can't help but think that an exhaust pipe is little more than an enlarged glorified tin can for exiting exhaust gases. Yes the best will have been flow and performance tested, but the OEM Audi one is not complete cack against the OEM exhausts of 'yesteryear'. Once it's knackered I'll put something decent on to replace the OEM, but am fairly convinced that Milltek aren't the only people to approach about decent pipework. Andy Oram's 450bhp S3 had a custom exhaust (to get round a routing issue) and it delivered very good results. Like you said, there is a lot of hot air on forums about people's personal opinions, but I'd turn that round and say that for every person who has a whinge, there are 2 people dickswinging about how their cars are logo'd up. Some of this very expensive kit can turn out to be as much about pure replacement than a definite enhancement.

I tend to over-service the car with oil, plugs, quality fuels etc..., and failing to do this renders the rest of your mods at risk/useless.

I totally respect your view, as without differing opinions out there I'd learn nothing and take nothing away to consider.

Mark , what sort of problems did you have?
I noticed that from rolling road results your car seems a little lower than comparison cars?
or was that sorted out and un related?

A ropey tick over, which may well be PCV related. I'm waiting on the BSH kit with the recent group buy to see if this settles down.

However with the Dbilas on it was misfiring at high rpms, also indications the car was running lean which according to stuff I've read on Vortex concerning similar symptoms is down to the incorrect MAF scaling on aftermarket intakes.

So for the time being at least I think it was wiser to go back to the stock airbox rather than risk engine damage.

Misfires are gone since I switched back, but the tickover can be a little erratic sometimes almost like it's hunting which leads me to think it's a PCV problem based on the symptoms I've read on vortex. No engine codes have shown up recently though I aim to check it out again tomorrow now i've been running the stock airbox for a couple of weeks.

APR have always been a little more conservative with their power output, I have no control over the boost/fuel/ or timing like the Stg 2 REVO cars do and based on the level of my modifications (all APR) it would probably benefit from some further development on their part to be honest. The REVO solution gives adjustable options that I lack.

However though my BHP is usually a little lower in comparison, the torque it is developing is at similar levels. It's no slouch on the road either.

I chose APR mainly because I'm close to Awesome and with the TFSi being a relative tuning unknown with some on-going quirks (in comparison to the 1.8T at least). I wanted to have some peace of mind that should I hit any problems they are close at hand.
