Spark plugs

When to change spark plugs. ?
In putting my car on. Dyno next week and I want to make sure it's in top shape. Injector cleaner? Throttle body cleaner?
Please help

Spark plugs are every 37K. I did mine at the scheduled 37 and then again at 60. At 60 I had to pay for that and an oil change and it came out to just under $500.

$500?? wow, you could DIY it and saved like 2/3 of your cost

OP, i always add some techron bottles before I change my oil, so that may "clean" your spark plugs, you can give those a shot. Or start running VPOWER if you haven't already...

I do a lot of things myself. Sometimes I have to weigh my time with cost.
