Just got a 2003 lancer es and i was wondering what the most functional...(street legal) aftermarket intake? i mean performance wise...

 

CAI (cold air intake)
or
SRI (short ram intake).

 

ANY intake will do the same thing. Be it an aftermarket $250 CAI, or a $20 DIY CAI/SRI.

 

what is the difference between short ram and cold air? from a technical point of view.

 

A CAI will gets its air from the fender well, where little to no heat exists. A SRI will get its air from the engine bay where temps. may be elevated at times. The difference in performance is not noticeable. However the theory stands that the cooler the intake air, the more dense it is, increasing performance.

 

If you car is an automatic than CAI will not fit because transmission is in the way. Only way u can put CAI on auto is by removing the batterey which can cause some dirty disasters so i recommend SRI if you have auto lancer.

There are plenty threads on this forum proving SRI is better than CAI. Also you dont need to worry about the rain or water going in with SRI.

 

ok so sri is the way to go then... the car is an automatic, and i don't want to relocate the battery so i suppose i have no choice...

 

what else can you do with an automatic... performance wise.... its the wifes grocery getter but i want her to be able to smoke the other moms....

 

Anything except CAI, clutch.

Then the rest kicks in. If you want it to stay N/A, then Headers, SRI, Maybe some plugs, pulley, etc.

RRm will provide you with most, if not all of those things.

 

hey evo jr tell me about your springs

 

just drop in a k&n filter save you some money

 

just grab a heat sheild from ebay ($20) grab cheap nice looking SIR off of Ebay ($25-$40) then grab K&N filter ($50) and swap your cheap filter with K&N, that is best good SIR for around $100. Less if you look around

 

I got an AEM dryflow from ebay and the filter adapter, thats all you need for now on intake. Exhaust mods dont help much, I would get the RRM crank pulley after the intake.
