on an LC you must use a 70-80mm silicone reducer.

The reducer will act as an additional velocity stack too :) see plenty of room for a silicone joiner!

I've always been skeptical at the effect a heat shield would make to our cars unless its covering the top of the filter heat rises and it will get sucked in anyway by the time it come out of the turbo it's up to the intercooler to cool it, having an air feed or under bonnet air feeds in general helps but power on our case is from increased gs readings and a nice straight flow through the maf and into the turbo...with adding meth I'm not hugely bothered about a heat shield just that the filter and maf are secure to avoid vibration and damage.

Quick question about the S2000 filter.....

T108 mentioned a 80-70mm reducer for fitting to the Cupra 180 models - however the filter part detailed in the link mentioned an I/D of 85mm.
Did the 80-70mm reducer do the trick, and it's just a type-o from the sellers?

Cheers

I fitted an s2000 filter the other day... Rang up to book my map in with AMD and they told me to take it of as will loose to much power from heatsoak, is this true as im liking the sound of it with an open cone on. Will it be enough of a power loss to worry about??

Open cones do suffer from heatsoak more than enclosed boxes do, but at the same time an enclosed filter has a limit on the amount of air it can intake compared to a cone. If cone filters caused that much heatsoak, nobody would use them would they.... just fit a heatshield to reduce the amount of heat soaked up by the air filter. I assume you live in the UK? therefore you'll be fine, ambient temperatures just aren't high enough here to cause any adverse effects in my opinion.
 
Not being funny but say the intake temp through the filter is 30 degrees for arguments sake it then goes through the turbo and comes out at 90-100 degrees it goes through an intercooler, if your intake temp with a heat shield that doesn't lower your temps by that much is 20 it'll still come out the turbo at around the same temp anyway... It's more important having a good gs reading and an adequate intercooler for the stage of map your running. Each tuner has a different opinion, did I not read niki from r tech recommend a free flowing open cone intake? After all he's managed some of the highest bhp from standard turbos to date...
 
Then again the world of the wonderful web is full of airbox pro's, this discussion really could go on and on and on....... Next rolling road day I'm doing both settle this once and for all, but then again there's what works on a dyno and what works real world, the sitting in traffic with under bonnet temps rising, so many variables..
