First, a dual exit exhaust (any suggestions??) and then either an induction kit or air filter. I was told that theres no point in getting an induction kit seeing as its an N/A and that it may even lose power due to some reason or other! However Ive seen a few people put induction kits on theirs so would like to know whats actually better for my N/A, air filter or induction kit? 
Unlike a front engined car we don't benefit from forced cold air filling the engine bay through the grille so an induction kit will draw hot stale air. The factory system draws cold air from the side vent and is designed to maximise low end torque. It's Toyota's million pound research versus 1950's thinking!waelwulfas wrote:so an induction kit will draw hot stale air.
Also you're compressing your air; the n/a's need as as much forced intake as they can get.[quote="waelwulfas"]don't the tubbies draw from the o/s and route he air through a longer system over the heat of the engine. quote]
It may lose a couple of horses but it will sound fantastic. Its not great for inlet temps but the sound is stunning when the TVIS opens. (not too sure if they have one designed for the MR2), which will allow the air filter to perform better as cold air will be fed towards the filter, but will still not be as good as an induction kit. What i want really is improved breathing and response in the low revs. Ive heard that induction kits will help in the high end but maybe wont benefit the low end response. From what ive read here, a filter thats positioned near the side vents to force cold air in sounds pretty good??RedMR²My Apexi sits right above the intake

I did mention this
