Whats ur favorite spark plug lol

[85mudbogger]

I have run the bosch plat 2, i disliked as for they liked to foul out and cold starting sucked
I changed to champions and was a lot better but after about 6 months they also fouled out and starting was a little better but progressively got worse, i know some of this is due to 11 to 1 compression and 93 octane and the heads arent in that great a shape but when it runs it run like a scalded dawg and the champions just seemed to not hold up to the severe duty

post up what ur running and why ur running them and how long have u had them,

I always rock ac delco's, cheap, and i've never had any problems with them.

x2 ac delco's....

39c/ea regular cheapie house brand copper plugs. Gap 'em by eye or with a hacksaw blade, change them all out once a year. Always worked great for me, then again, I only own old beater v8 cars, lots of room to change plugs. If it was a 6 hour job to change plugs, I'd be ponying up for 100k mile whatevers

I used to run NGK plugs in my 70 Camaro with a built 10.5 to 1 350 and they really seemed to work good.

Rumor has it that's who's making AC plugs nowadays, would make sense that NGK's work good.

I use AC's as well. Got a screamin' deal on a bunch of them (24 or so) on ebay awhile back, like $.50/plug.

i have always run AC delco in a vehicle and NGK in all my bikes.
when the 454 is done, its getting NGK plugs.

x2 ac delco's....

X3... I've tried the fancy bosch plugs and they all fouled out on me within 6-8 months or so. I went back to AC Delco and don't have any problems.

I'm happy with autolite plugs. Never had a problem, and have run them in just about every vehicle I've ever owned.

 

[85mudbogger]

how bout some part#s on ur ngks , which heat range u runnin

 

[4X4HIGH]

Ever since i first ran an NGK V-power plug about 15 or more years ago i will never run any other plug again.

EDIT: Current engine uses a UR-5 NGK plug.

I use strictly AC Delco's, i have NEVER had a problem with them, and they last a good long time.

I have tried the cheaper Bosch, Platinums, ones with multi points, whatever, nothing has lasted as long, and as well as the AC's have,,,,,well, there was one set, but i got those for free,
I didn' notice any power increases, of fuel mileage gains, but they did work for their standard purpose of creating a stable spark, and actually i ran them for almost two years before i just decided to do a tune up> They actually were not that bad, the edged were alittle rounded, normal wear for a sparkplug though.........Splitfires.

Too expensive to go buying a new set though especially when AC's did just about, if not the same job Splitfires did.



So yeah, yet another vote for AC Delcos

 

[blazin_blazer]

i agree

I'm happy with autolite plugs. Never had a problem, and have run them in just about every vehicle I've ever owned.

not sure if they still do it, but autolites used to carry a 100,000 mile warranty!

 

[pauly383]

I am running Bosch now , and no problems , but will switch back to AC Delcos next change .

When I was a kid , I swore by Autolite plug # 145 ( truck and marine ) in all my small blocks in AZ .

im running 7 ac coppers (because i like them) and one bosch copper. cylinder 2 plug got hit with some offroad debris. what are the chances? i had my old set of bosch plugs (49cents apiece with coupon) with me for spares and popped one in. good as new. decent plugs. i'd have no problem running bosch again.
