K+N v's Green air filters

[jase750]

Well today with the weather being so terrible I decided to clean the air filters out in my car(green) and bike(K+N). So after taking them both out I noticed a few differences.
the rubber around the Green was a lot more soft and plyable than the K+N which had gone quite hard and stiff.
the metal gause on the Green was in better shape than the K+N
And the actual filter area was less encroached on by the rubber around the edge, that is to say the actual rubber seal on the K+N had "bled" onto the filter area more.
the Green filter has done a total of 70K miles in 3 different Ibizas I've owned
130 sport,100 sport and my current 130 FR
the K+N has only done 18K in the bike from new.
So on the whole I would say in my personal opinion that Green are better made and last longer than K+N.

My green filter has been used for probably around 100,000 miles in 2 different fabias.

It's about to be ditched for a BMC CDA, but not because it's worn out or anything. Still in very good nick - It's just I'm losing the stock airbox.

I don't think it would be fair on the K & N as you're not making a like for like comparison.

I'm not a grease monkey and ride bikes, but I would assume that because of the proximity of everything on a bike (within the frame), parts are subject to more extremes in temperatures.

Probably a lot colder on the move and then much hotter in the trafic due to proximity again.

The only bike related example I can give is that after some time, the middle fairings round the engine can become very brittle due to these extremes.

Filters are also right on top of the bikes engine whilst on a car possibly a couple of feet or so.

I think you might be a bit harsh to Mr K & N.

Incidentally, my mates Gixer thou runs a bit warmer than the rest of ours. Coincidence?
