my 01 wrx performance seems sluggish !! the boost selenoid and pipes seem fine! is there anything else i can check ! air filter is new and its only done 24k. is it anything to do with parts of the breathing or turbo system? cheers all.

 

If standard .. then unsure.... if modded then possible the plugs could be starting to degrade after even 24k..

Only an idea

Cheers
