Post 99 RS seeks heavy breathing intake...

99 RS seeks heavy breathing intake that doesn't lean out or break $300 MAF's. (real life experience necessary).

In all seriousness - does anyone make an intake that can work with the 99's standard ecu and MAF - and still make a few ponies? JC Sports? Weapon R? Anyone have any real life HP expectations?

Pre-Thanks

I believe both rallispec and larry ganz have intakes that work with the MAF on MY99 but I do not know for sure if they tend to cook them or not... anyone with actual experience?

What about running lean - do all the intakes do this? Is there one that doesn't? Any real life experience?

Thanks

You are going to run lean no matter what. It is an ECU problem, not an intake problem. In order to correct it you need a SAFC. The car only runs lean at WOT. Unles you drive at full throttle all the time, you really won't have any lean running issues. Have fun!

Any Impreza intake can be adpated to a '99 with a minimum of work and a couple of readily available additional parts. Please do a search, this has been covered hundreds of times.

I'd go with the JC Sports one, it so far has the longest track record of working w/o causing the blowing up MAF's.

ISR's intake seems very MAF friendly. I have it on my 99 and its very solidly mounted. Look into it. I can send you pics if you want to see it installed. I have added a custom made heat shield for it, and I love it.

Thanks for the real life opinions. I'm used to setting up HO v8's with carbs and distributors, the computer stuff is new to me. Does anyone run a Apexi S-AFC? Did anyone install/configure it themselves? How hard is it?

Thanks as always

You can get a a cone filter conversion kit from www.imprezars.com/spectrum.htm#filtermaf that doesn't need an AFC and improves breathing of the motor.

I am trying to finish up a similar intake that uses a shielded cold air filter but the 3" maf adapters I am getting at wholesale cost are held up a little longer.
