K&N filter is great. Most G's and Z's drop them in.
Noticeable noise difference too.

If you want a new intake, just get an OEM Z-Tube and or Pop Charger along with it.

 

agreed. Get a z tube and pop charger.

 

 

Wrong....^....sorry fForce! Although Pop Chargers sound good, in warm weather they'll cause you to lose 30% HP due to "Heat Soak!" You need to make a decision if you want pretty or functional with no loss in power. Z-Tube is a great idea, totally changes the way our coupes sound. Then all you need is a K&N or AMSOIL drop in filter so she can breathe better....Gary

 

30% saaay whaat. I guess it doesnt get that warm where im at so i dont notice, do CAI's make you lose power when its warm out too? And how warm are we talking

 

Maybe you don't have the "HEAT SOAK" issues in the frozen north but anywhere across the US where it reaches the '80s and the surface temp will hit 100+ degrees Pop Chargers will cost you HP. Any intake with metal tubing will cause this issue. Stillens CAI is not effected because of the plastic composite construction and why I keep one as a alternative for my Fujita intake....Gary

 

Ok ya that makes sense, I always kinda felt like my car drove a lot nicer on cool days and evenings, thought that was just me though haha

 

Well you lose hp in any weather with the pop charger. Not really from a roll, the problem is when you come to a stop for any amount of time, the popcharger soaks in all the hot air from the engine and does so until you get fresh air flowing into it at maybe 15-20mph. At speed should pretty much be the same, but if you race anyone from a dig or at the track it's going to cost you.

 

Is the nismo cold air any good. Asking because my car came with it when I bought it.

 

I live in Michigan so we have cold winters here, I'll just replace the filter with a K&N for now, and maybe go with the whole intake setup next summer

 

Get the stillen z-tube/air box!! I have it and love it!

 

I had not thought of the Heat Soak issue, thank you Gary. Always have amazing answers!

 

I drive in high heated areas and have never noticed this heat soak before. I won't say it doesn't happen, just not enough to where I can tell. I also never race, so it doesn't matter to me..

 

This question has been asked 1000x...now its 1001. Research.

I didn't notice any noise difference with my K&N drop in for the year I had it...barely with ztube.

30% is not an exact number. But yes short ramis suseptable to heat soak. The stock air box on the G is well designed, any gain from any intake on a G is negligible. Sounds good from what I hear though. I have a turbo G and my intake filter is located in the drivers side mesh area of the sport bumper...good fabrication I think.
