AC Delco and Motorcraft are $hietest spark plugs person can buy. And I mean if there was award for crappiest quality spark plug those two would probably get it every year. Thats my experience with them.
really? i was a mechanic at a gm garage for years. AC was the only thing you ran in a gm. anything else made it skip like crazy. Also our brother Ford dealer next door didn't put anything but motocrafts in a ford,lincoln, or mercury. same as the gm's, wouldn't run right without them. most dodge owners and shops i have talked with tell me champion is the only thing they recommand for those.
this thread was very usefull for me chris. i'm a fairly new(and proud) tacoma owner was was looking for this very info. thanks for the intel!
brand specification for the plug really depends on the vehicle and application as chris stated. its really best to go with the oem parts. or talk with someone that has done there homework as chris has done and find out what other options you have.
location, weather, and driveing habits all play a huge factor in this as well. hence again, you can't go wrong with oem parts which have been designed and tuned in conjuction with the engines and ignitions to handle a variety of drivieng.
some may have luck with other brands and some not. bottom line. oem will get the same results each time across the board.
thanks again for the info chris. and all the laughs from the other posters. lol
