I need help with a prolem I have People. I have a JDM sti bugeye. It has a zerosport exhaust, 255 fuel pump and a hayward and scott decat and its getting remaped next month,, My problem is with the air filter. some people say leave the panel filter in and others say fit an induction kit.
Any help???????????????????

 

i had one of these on mine very good http://www.airpowersystems.com/wrx/my01/hfa.htm

 

You only need to change to an induction kit when your looking for 400bhp give or take and that is so that you can fit a FMIC. So an uprated panel filter will be fine.

 

its not worth putting a short ram one in as it just sucks hot air from the engine bay in, but there is a benefit of fitting a induction kit in the wing, referred to as a CAIK, cold air induction kit.

 

Just fit a good air filter, STI (though quite expensive and a service item), cosworth (also a service item), K&N, Green etc (both reusable).

Not worth it it unless going for 400bhp mate. 350 and just above will do just fine.

Best ones I personally think worked well.

Green
TSL (Green) Grp N filter

That looks a trick bit of kit

Not sure about the size of that cone filter, looks abit small or does it need to be to fit the inner arch

Ive an sti five an think they were originally designed to fit that.

 

K & N panel filter personally ,bought my 1st one in 1985 for a 2.0 ltr sports capri ,and have bought well over 25 up to current day,never had a problem .I currently have one in my impreza as well as my honda civic & wouldn't buy anything else.

 

The filter isn't as small as it looks, it's a good bit of kit, Andy-F even commented on how good the airflow was while mapping my car.
