Airfillter
 

Hi just to see if i can get a bit help.I have an sti8 that has a proven 324bhp. I have just fitted a full 3inch exhaust system from the turbo back (to replace the 2 1/2 inch that was fitted) and its booked in for a remap with Andy Forrest.I havent checked yet if the car has a sports panel fillter fitted but if not should i get one before the remap or do i get an induction kit??? if so can anyone tell me the best makes and where is the best place to get them from.I have also been told im best to change the plugs to a grade 7.But the ones that are fitted are a grade 6 and have just been fitted by subaru.Thanks Sean

If you're going for a remap and want an IK then look at https://www.scoobynet.com/group-buys...d-air-kit.html

If you want to stick to a panel filter then get a Green, K&N or STi version.

Definately change the plugs to NGK PFR7B's

Can i ask why the plugs would be better getting changed (only out of intrest).And where is the best place to get them ?? Thanks

i believe you change from pfr6b to 7b because they can take higher temperatures
