I just bought some Autolite Double Platniums. Anyone else running these, or have a better spark plug option?

 

i run em. love em and price is reasonable.

 

That's great to know because I got a 98 with a 4.2 that i need to do the plugs in and was looking at those. Sure be nice to know how well they work.

 

I bought some new plugs for my '02 5.4. A guy at Jasper engines warned me the stock plugs would probs pull the threads with them, causing expensive head repair. Anybody had this problem?
TIA,
Mark

 

i put em on a year ago and just checked em the other day i drive 20 miles thruway to school every day for ~7 months and the rest is city driving. plugs looked great no unusual burning just looks like its throwing a nice hot spark in all cylinders

 

I have heard the same thing quite a few times. I had one come loose a while back, and it threaded right back in
