Renntech Spark Plugs!!!

I just ordered new spark plugs from Renntech. Does anyone has them installed?? I would appreciate opinions on it. I had one set replaced (original set) after getting stock in middle of nowhere 6 months ago.

I am taking my car to Renntech dealer in LI close by and they will put them in for me. Also those plugs were like $350 and I think thats what dealer charges for the original ones. I just hope they work and I dont get stuck anywhere specially with the newborn that my wife and I just had. I had that happen once and cant have that anymore.

First off congrats on the newborn thats awesome! i know the feeling, where you from? And the stock plugs i paid $120 for from Mercedes.. I'm sure any new plug will work just fine, and what are they charging you to install cause Helms Bros Mercedes is charging $240 just for labor

I never asked what they will charge, this place TKX performance always takes care of me and are fair with everyone. I just need to fix this issue so it never happens again.

i installed 2 steps colder spark plugs (stock is 7) months ago that are designed for +1000hp, and didn't refer to anyone, did my homework untill i found them, and you need a special tool. so i think maybe Rentech are using the same now.

i drove 15k km on them till now and about 5 months. witout any problem.

I really really abused the car in these 15k


in their website, Renntech are using NGK and if i am not mistaken, they are using 1 step colder.

EDIT: sorry i don't think they are using the same ones as me because i am not using NGK.
