Air Filter - ZR-1 Net Registry Forums

JimZRyd · 11-10-2013

So what do you guys feel the best choice in filters is? K&N ? Recently bought one of those snazzy air box covers from forum member higgyburners and wanted to change the filter at the same time. Also will be adding headers and new exhaust in near future as well. TIA!

clean factory filter is fine

LGAFF · 11-10-2013

I have heard a lot of people running their Zs on the dyno sans filter....any know the weak point of the air intake?

Dynomite · 11-11-2013

I use K&N

Stainless Steel Air Box and Air Filter (L98 and LT5)

K&N 33-2035 High Flow Air Filter

Thanks guys! With my old C5 there were probably 1/2 dozen or so different brands to choose from (I went with a Halltech system). I have also read were some people were unhappy with the K&N citing that the filter material was too thin to capture certain contaminants and thus could cause engine contamination, this is what I was concerned about. Unless I can find a better brand I'll be purchasing the K&N.

the factory filter is fine per mark haibeck. I worry about the K&N oil fouling the motor...happened with my mustang

My 2 cents. Go with a stock filter. K&N won't give any more HP and wont filter any better than stock AC.

I think this only occurs with a MAF sensor car....

Its been my experience those that have issues with K&N are the type that think "too much is just enough." MANY people over-oil the filter and then wonder why its a mess and gets into the engine.

That being said there have been serious debates (and supposed research)about how much, if any, performance increase a K&N filter (or any reusable/re-oiled filter) provides.

Nether is a bad choice depending on your own personal maintenance habits.

There's another brand similar to K & N, half the price, works just as well - as long as you don't over-oil; it can foul MAF elements as LGAFF said...

I keep 2, so one can dry while the other is ready pull pull air.
