First of all, how often are you checking them? When you yank a plug, and it "looks like new" how many miles are on it? Stock engine? N/A, nitrous? etc etc.
Right now, it sounds like you're a bit lean to me, and really has nothing to do with the plugs.
Give us some more info, and we'll go from there, K?  |
I check them about every ten 1/4 mile runs (Track only car)
These plugs have been in the car for over 100 runs and still look new.
I had Box stock 192cc Canfield heads, ported cobra intake and an E303 cam on a stock short block.
My new set-up is The same 192cc canfield heads with a 5 angle valve job, blended bowls, unshrouded valves and minor port work.
Custom Flowtech Induction cam .566 lift 218 duration @.050 intake
.............................................566 lift 224 duration @.050 exhaust
Same ported Cobra intake for now all on a 30,000 mile stock shortblock.
I was worried the car was running lean before so I may really have issues now.
I am going to the track this Friday to try and get the new set-up dialed in as far as the timing and fuel pressure go. The only dyno here closed so i am going to have to tune at the track.
