So if you know I put in a nitrous kit in my 07 4 months back and today i found out when taking apart my spark plugs that i blew 3 tips off 2,4,6 cylinders and hanging off on cylinder 3 and no where has 1 step for the 07's and still waiting for order on my plugs from the dealership.....nitrous is fun till you break something but thats life when you want to go fast lol

 

hehe... it happens. I check mine every oil change for that reason.

 

ouch...


i wonder where the tips went??


get some colder plugs, you can probably cross reference them with another plug..

 

i bet the tips melted.

 

Make sure you arent using Platinum tipped plugs with nitrous, also to go along with the colder plug, the gap should be shorter as well. dont blow money on expensive plugs when you are spraying, I loved the $3 NGK's 2-3 ranges colder then stock with a tighter gap, depending on how many bottles I would go through I would change them anywhere from 10k-25k mi. Platinum tips will break though, they were designed so that the manufacturer could say 100,000mi till tune-up......nitrous optional

 

im kidding, i bet the tips are welded to the top of the piston..


seen it many times before, also they will try to get down the side of the piston and really scratch up the cylinder walls.

 

coppers work the best for nitrous. they are only a few dollars each as well..

 

yea i bought coppers from the 06 model but the threads are not the same they are different and noone has them right now

 

I thought the 07 Z's came with Iriduim plugs already.....
