Anybody tried using the Pulsar Spark Plugs in there Escalade? I'm getting ready to do a tune up and trying to get some info either good or bad on these.
I tried to post the website but the forum won't let me
Have never used them, I have used in all my LS engines NGK Iridium plugs
Notice a difference between those and regular spark plugs?
They just seem to last and last compared to the standard plug

I have to agree. NGK Iridium plugs is the only plug I have ever put in a LS engine as well. Get some good MSD or Taylor wires to go with them.
Well after doing some research I think I'm going to go with the Bosch Platinum series, just trying to decide between the Platinum+4 or the Platinum IR Fusion. I do alot of towing and alot of driving in general, I put about 30k on my truck a year. Whats the benefit of going with the Iridium plug over a straight platinum plug?

On our trucks, nothing except longer life. The iridium plugs have a smaller center electrode diameter making them easier to ignite requiring less voltage and harder for corrosion to build up. Generally, this is only critical in situations where firing the spark plug becomes difficult, i.e. high compression blower or nitrous motors.
