Recently purchased blaze yellow 02 wrx with 80K miles. Fully stock
I'm looking to upgrade the air intake, looking at cobb sf intake, airbox, and post maf hose
Wondering if there are better options, or if it's required to etune with ecu before changing to different intake

Thanks

I’ve heard the old WRXs supposedly don’t need tunes for intakes but I’m not 100% sure..

Appealing to the extreme, if you put your MAF into a 10” intake tube I can’t imagine it giving a useful reading at all the stock computer could handle so I’d be wary..

I’d probably only go with the SPT intake myself unless you have a wideband and know what your looking for to spot a tune problem..

If you have a wideband I’d say get whatever you want and see what AFRs you get, and maybe need a tune if your AFR goes off on you..

I would get a Cobb tuner before anything It does need a tune after I have a bugeye sti even just an intake it runs like crap and you have a more of a chance of knock of you wanna reduce knock don’t add more air flow without telling the computer otherwise and make sure you have afr gauge and have your maintence done even just an intake these cars are awesome keep them alive
