  3. General Maintenance, Troubleshooting & Accidents.
    I am looking to do a tune up on my 06 wrx this weekend, and am curious if anyone has used the E3 spark plugs. They're supposed to give a better burn increasing fuel economy and hp. I would install them on a n/a vehicle in a minute, but not sure if they are the right thing for my wrx.
