I have TR6's for the N20 and will be dragging this car at the track this time tommorow night.

Will these plugs fould if I have to drive on the highway for 45 min to the track? I have 16 of these plugs so if I pull a few and they are fouled...I got some spares.

Also, if they fouled, won't they just be burnt to crap or just all gunked up from fuel??

 

I doubt you will have a problem I run a colder set in my car and daily drive it no problems or fouling.

 

No, they wont foul, just one heat range colder, when you start stepping 3+ range then worry bout it.

 

If the TR6's foul you have bigger problems.

 

Thanks you guys...sounds good
