I got new spark plugs about 13,000 Miles ago.

Ever since the truck has been starting hard, not idling like it used to, and just feels like a lack in performance.

These plugs are Bosch tripple Plats, I've heard (And know from expirience) these plugs don't go too well in these trucks. But will I see a noticible difference If I change them out for some Autolite/Motorcraft Douple Plats? Is it worth the effort and $20. Or should I just go about my day until these plugs crap out in about seventy, THOUSAND miles ?

It's kind of disappointing because I know the truck could feel better, but is it just a pet peeve kind of thing? Or is it not actually good for the truck....

Any feedback would be much appreciated, thanks

 

i would change them, you might want to look at the denso iridiums, they are alot of $$$ but i love mine and it idles smooth as glass, good luck

 

change the plugs, it's worth it, and check your wire set, you may have a problem with one wire that is causing all these problems.

 

i like my NGK irridiums holding up well!!

 

Denso Iridiums or NGK Platinums are some of the best spark plugs.

Make sure one of your coil packs isn't bad or the wiring is slightly damaged.

Are you noticing a drop in MPG?

 

No, the truck still runs alright. And Gas Milage hasn't dropped. Getting around
14/15 City and about 18/19 Highway.
