Still prepping to get everything put in for the procharger install and was getting new spart plugs, and on lethal performace i'm seeing that they don't offer 4 prong spark plugs. the best they have is 2. Wouldn't 4 be better to ensure that spark is pointed directly to the cylinder? or am i wrong on that?

NGK TR6 with a 34 to 36 gap. those 2 3 and 4 tip pluga are all a joke to get people to buy them

Yeah - after trying everything - the NGK TR6 or TR55 - depending on the heat range you need (base off your boost level) I'd go with the TR55 unless your above 10-12 psi. Or whatever Motorcraft plugs are stock for your engine.

They actually do work - and dyno - the best over any other plugs.

dont buy bosch have had terrible experiences

well i got this because back in the day, the old schoolers would mark their spark plugs to rotate them so they directly fire into the cylinder, thus why they made the 4 prongs.. you say it would make any difference it the spark plug was fireing away from the cylinder?

Not the cylinder. They aimed it at the intake valve. And yes, its a waste of effort. You won't get anything out of doing this. Its a good theory, but just not helpfull in actuality

alright guys, thanks for the info.. wont' waste the time.

The multiple side electrode plugs are just a marketing gimmick, as others have said.

besides it being a marketing gimmick is there actually any downside to them? not saying they are better or anything ive used +4s in previous cars and didnt have any problems didnt see any benefits either tho

there is no real benefit to running plugs with multiple electrodes b/c it is only going to do 1 spark not 1 spark to each electrode dont waste ur money
