Hey guys what spark plugs do you use. I hear the orignal AC Delco are good platnium. I also heard people say NGK are good, but they have like 3 diffrent lines, which I am told the Delco's are still better.
I also hear everyone talk bad about the boush platnium plugs.
So I am confussed.......

 

Yes Bosch's are ****. I had them and it caused misfires. Im now running NGK TR55IX iridium plugs they are $6 something but they are nice and last longer than regular NGK 55's.

 

Just changed my plugs last weekend, at 113,000 miles the stock A/C platnums were still fine, all pucks in place and gap was still in spec. I installed NGK TR55's (regular copper core) for $1.49 each and happy with the results. I personally like the A/C and NGK. As for BOSCH, wouldnt use them.

 

So far the NGKs are what most use. Get the cheapies, copper NGK TR55s if you plan on changing plugs once a year or go with the NGK TR55VX (plats) or the TR55IRs iradiums if you don't mind spending the 50 bucks and don't want to change your plugs for a long time. JMHO

 

With a near stock motor, I would suggest you use a platinum plug so you don't need to change them as often as a copper plug. I tried the Bosch when my motor was near stock and it ran like sh*t.
