Hey Guys,
I've never used this before. What I want to know is if Ive put a new set of spark plugs on my car will this damage the new plugs if I run half a can through the manifold like people say to do so ?
Also after spraying the cleaner how long should it sit in the manifold before running the car ?
And once the car is running how long should it be run for before repeating the process if need be ?
Also what should I notice if I do this upper eng clean ?
Cheers
