So ive read that ppl dont recommend Bosch spark plugs. A buddy of mine gave me me some Bosch Superplus spark plugs for free would u guys recommend i use them or just save up for something else???? Has any one had bad experience with them???

Ive used those on my bone stock Trans Am I had no issues what so ever. But I would investigate more before using them. They worked for me.

NGK's... I've had nothing but bad luck with Bosch plugs. Just stick with a Simple NGK Tr55..

I've used Bosch, Denso (stock from GM), NGK, and Autolite. They all worked.

Just so they're the right heat range you have them and they were free. Throw them in and see how they run. If they run rough, pull and replace with another

Im not a fan of them people have preferences but if you have a performance motor pretty everyone can agree on ngk's being top notch no matter what the build or application

Just installed the Bosch Ir's last week, replacing the stock AC Delco. Had the Bosch plugs and wires laying around, so I thru them in. Not bad. But I am switching to NGK TRT55s once I get my headers. The Bosch are comparable to AC Delco. But I still prefer NGK TR55s and MSD wires.

LS1s don't use a waste spark ignition, which is where the shitty Bosch reputation comes from. They DO NOT work in waste spark systems. However, this does not mean it's OK to run them in other applications. They're overpriced and poorly designed. You can find better for cheaper.
