Back to Back Comparison: NGKs vs ZR1 Plugs
Hey guys, this has been a hotly debated topic around here it seems, so I took the time today to go ahead try out both sets now. So, the plugs were swapped today, and in 300 miles I'll pull a plug in the ZR1s for comparison in regards to cleanliness. Anyways, here's the NGK after 300 miles:
So, not too impressed. Quite a bit of loose soot around the plug. Now, on to the driving impressions. All I can say is WOW! I didn't think that $80 of spark plugs would make that big of a difference. The car idles better, comes off of idle better, runs at lower rpms better, and pulls harder too! You can't hear it that much with the iPhone recording, but here's the before idle: And the after: So, in short, if you run the NGKs you're a loon This has been a not so important message from your mostly reliable Camaro brethren with too much time on his hands |

The difference is actually noticeable between the two videos.. Spark plugs do make a difference..

I never thought so, but after swapping them I sure do.

If you need to go even colder than the ZR1plugs, I'm having real good luck with Brisk GR12S plugs. They are really cold for nitrous and boost. The GR14S would be good for alot of boost or alot of nitrous. Normal size boost or nitrous and I too would run the ZR1 plugs.

I was running 2 steps colder, and I make 16 pounds of boost already. The ZR1 plugs are handling the boost better than the colder plugs at this point. Doesn't take a few cycles of cranking to start now either.

I wonder if I could get away with ZR1 plugs. 12 psi and now a 125 shot on top of it. Stock compression and stock L99 cam, 93 octane E10 no meth.
I have a feeling the ZR1's would be a little too high of a heat range, and since they are protruded they are not optimal for nitrous. Good for one or the other but not sure when running both nitrous and boost.

br7ef if using nitrous. the thread cover the tip and helps with not blowing out the spark. i accually think my car runs and idles better with ngk's
ive got enuff plugs to run 10 cars a life time and swap them out quite a bit. i really like the br7 over anything else for nitrous on 100+ shot. but when it comes to blowers and plugs that i cant say nothing about.

You could definitely use the ZR1s with nitrous and a blower or only nitrous. I'm pretty sure Jamie also uses these plugs with his Maggie/Nitrous car.

Just not sure if I should go with the ZR1's, the Denso IT22's, or the Brisk 14's. At this point I'm still thinking I should avoid the protruded electrode of the ZR1 plug. Decisions...decisions. PS: I don't want to do what Jamie is doing, his car is slow. LOL

I had misfires with the NGKs when starting, idling, light throttle, and returning to idle. I hated those plugs. I'd give the ZR1 plugs a shot, the $80 plugs made one of the biggest differences on a stupidly expensive car

You said it idled better with the ZR1 plugs. With them being a step hotter then the BR7's would that be the reason it idles better?
