I'm going to replace the spark plugs on my 99 1.8T.
I am a shadetree mechanic at best, but I need to keep my maintainance costs down, and I'm willing to turn a wrench to do it. I had all the belts replaced by a reputable mechnic (including the TB), but a couple months after that I noticed a drop in performance, and since I'm pushing 90K miles I think it's time to replace the sparks, filters and maybe even the wires (opinions?). There is nothing in the owners manual recommending brand/type of sparks, other than to purchase it from my AUDI dealership. Yea, sure I'll do that.... (not).
Could someone please recommend a brand/type of spark, and also please let me know the torque setting required? I live in the USA. Thanks !
