Question:
The spark plugs are running just fine, but someone said that GM's use delco spark plugs. Is anything going to happen because I chose to use Bosch spark plugs? I chose those because the associate said I didn't have to gap them.

You can run any kinda spark plug you want there are many brands. You are fine.
My 1987 Jaguar XJ12 is misfiring. Any ideas why ?
bosch is a better brand than AC Delco. It doesn't make a difference.Brand isn't important as long as the size and threading are correct.
As for "gapping" them - that you should have done even though the associate said you didn't "have to." Proper gapping insures long-term performance of the "spark" ability.

as long as you use a good grade plug you shouldn't have any problems. you should always check the gap on your plugs when there put in. if you check yours you will see there not all the same.If it is running fine do not worry about it. I always use what the manufacturer would put in a vehicle. But again, if it is running fine, do not worry about it.
Need help with 98 Olds Silouhette, Can you help?
gm comes with delco you can use any brand. but bosch sparkplugs are very poor quality, i would use a/c or ngk. etc. bosch plugs break alot. more than any other brand i have ever seen. ngk are really good quality plugs. get platinums.just for some future wisdom always check your gap. you never know if someone dropped the plug or what have you. not to mention not every car is gapped the same. so always check. as for plugs, not all plugs are the same. there are some plugs built w/ better metals,ect for performance(spark) but for your application you won't ruin the car. i would check your gap if you know how.
When you clean the inside of your car,what steps do you go through to make sure it comes out nice?
Brand name Vs. Generic. General Motors always uses AC Delco parts. I've gotten 100k miles on a set of them. Many will say Bosch is better, Some will give you a different brand name, The worst thing that will happen is they might wear out sooner. I've never seen a measurable difference from one brand of spark plugs to another.I am thinking of replacing the engine of my honda by a GM 2.8 V6. Is this possible...?
I do believe Bosch makes a better auto part, on average than most other manufacturers for the average street vehicle. But then I may be biased, I was an engineer for Bosch's Braking systems for several years
why will my automatic car not reverse?
Bosch are fine. Probably better than the Delco - I bet they werea little more expensive.
take them back out and check the gap. sorry but it needs to be done
