I bought Bosch Platinum 4201 from pep boys today for my 97se. Are these pre-gapped ? If not does anyone know what it should be. Thanks

 

.042, is stock gap. my bad, .044 is the right one. its been awhile.

 

.044 is stock gap. But you should throw those crap bosch plugs in the trash and get some NGK coppers.

 

so after reading the last post i guess i will buy better plugs. I gapped 3 plugs and installed them and car didnt run smoothly so i didnt bother to put the other 3 in. I took them back out and re-installed the originals until i could buy some ngk's. But now car still runs a little rough and my check engine light was flashing. And I am talking like 30 times in a row then stay solid for a minute. Any ideas what the hell is going on with my car.

flashing CEL? probably something serious

 

.043 is the proper gap, hence the -11 in the model name.

Bosch makes good stuff............................................. .........................for me to poop on!!

 

the -11 stands for .044 not .043. Either way stock gap is .039-.044. Get rid of the ****ty bosch plugs and get NGK, you'll thank me later.

 

The gap on ALL platinum plugs (regardless or make) are pre set, no gapping required.

 

Please delete that post before you get flamed to death. Yes plugs are pre-gapped from factory, but during this thing called SHIPPING the gap is likely to change. Anyone who doesn't check the gap before putting in the plugs is a moron. Next time you open your mouth make sure you're correct.
