Hi Everyone Just saying hello!
I've had my 07 wrx for a while now, and just recently a friend got rid of his subaru and took his parts off and installed them for me, an injen intake and blitz nur spec exhaust. I think i made out pretty well by only paying 300 bucks for it. But i've been wondering if i should have done anything else before adding them on? Car has been running fine except for a CEL which came on. Got it checked out and cleared and it seems that cyl 4 was misfiring. I have an appointment to go get new spark plugs changed because they were due anyway. At 50,000 miles in 2 years i've done alot of driving.... And i've also been wondering what's the best synthetic motor oil to put into the car? My friend keeps saying to put synthetic in, but he fails to mention which one...each time. So any Suggestions?
