Spark plugs

[MFC44]

How do I get the plastic covers off of the plugs. I removed the harness and marked it to insure right placement back. But then when it try to remove the caps covering the plugs it fells like I am going to break it. How do these come off. Thanks for any assistance.

Got the new plugs from Dennis Kirk they where stated exact match but where not. The top side that sits in the ignition coil is a little bit longer so it will not seat properly.

Yes or try Bosch 4 electrode I have been running them in the turbo for a season and put them in a buddies Nytro and they do feel better I went up to a CR 10 also

This is what I run. Stock in Phazer and supposedly worth power in Apex. Now in my Viper with about 4000mi on them. Highly recommend.

I ran cr10ek in my nytro and run them in my viper as well.

I can understand running a cooler plug in a turbo or highly modded sled but why go cooler than stock on your Vipers which are known for starting issues?

I ran them on my modded nytro with no issues, so I figured I would run them on my viper, and still no issues. I was lucky even before my reflash I only had a few start issues.
