It's about that time to change the plugs. anybody running these? Experiences, comments- recommendations....................

 

Those are the plugs for a ctsv/zr1 right?

 

Don't know what they're 'for'~ heard some good things about'em and they're the correct gap and wanted to check here first with those in the know..............

 

I run them. No complaints here. They are suposibly the replacement plug for the ls engines.

 

That's what I'm gathering- for all LS engines; 4.8 thru LS2....................

 

I've used them, they're "platinum" replacement for the LS engines. You won't feel any difference but they'll probably last you a few thousand more miles over the regular Delco replacement.

 

Cool. One more thing, replacing spark plug wires. It's not like the wire wears out- ya don't see utility companies replacing power lines. Other than the outer jacket getting chewed thru- really, an honest question.................

 

The rubber will eventually get brittle but hard to say when. I pulled the engine on my 182k mile Suburban and re-used the same wires... just depends on if you want $40 worth of piece of mind or be cheap like me.

The short ones on the coil pack engines are not as prone to issues like the old rat's nest out of a dizzy cap. No headers to catch on or valve covers spewing oil all over them.

 

That is because they are bare wires. It is the insulation that wears out on spark plug wires.

 

I had these and will not buy again. The gap blew way out after like 20k over the course of year, cause random misfires and idle issues. Replaced with TR5's and much better and way more affordable
