hi guys, need some advice. thinking about fitting a k&n typhoon short ram induction kit to my 04 wrx read these are supposed to be good due to the fact their enclosed with a heat sheild. looking for advice, anyone got one fitted to their car without any running issues? is the maf safe? know these are weak point as i'm on second one running standard induction. would it need remap? currently car has blitz nur spec r exhaust and hks dv. know i could just fit panel filter but just love induction noise from induction kit

I would say that you would need a re map for the maf to function properly and stop the car running lean. The maf sensors are sensitive on these cars and sure that an ind kit is only needed when runnin big BHP, 380 and above I think.

standard airbox is good for 350 bhp, you'll need a remap if you add the induction kit as you'll be sucking in more air hence and will be running lean. I've got a standard airbox on my 05wrx and am around 340bhp

thanks for advice guys. what panel filter you running? if i decided to have it mapped with induction kit would i get much gains?

Im running a green filter in the std air box and 3 inch exahust system with 348BHP from my 04 sti

Unsure what is the best ind kit and which gives the best gains, best to speak to a mapper and tell them you plans and they will keep you right.

green for me too

If you had your car remapped, and assuming it's either standard or very lightly modified, you would get a gain, but the gain would be from the mapping, not the induction kit, if that makes sense.

Or to put it another way, if you shell out for an induction kit and a remap, you will end up with the same amount of power (near as makes no difference) as what you'd get if you'd just shelled out for the remap and left the intake standard. As has already been said there's nothing to be gained in changing this area til you're well north of 350bhp. Good panel filter's more than enough.

+1 with Split on this

Im running the K&N short Ram, I ran for near a year with no MAF issues before getting a remap.
The only issues it ever caused was surge, moving to a MD321T solved that problem though.
