I bought a set for my 06 but have not put them in yet. I did run them in my 05 rx1 and had no issues, but I have heard that they can foul easier and with it being a slight pain to change them I just never put these in the apex yet.

I don't see how u don't think it would u think it be hotter bc ur geting a better spark

I believe the cr10 is cooler than the cr9

 

[gytrapex]

Me to u think so much a lot of ppl online say the run hotter bc u get more of a spark out of them idk how true it is

I believe the cr10 is cooler than the cr9

The lower the number, the hotter the plug. I guess that's why the 10 would foul easier. If you go with the 10's just make sure to warm up the sled good but don't let it idle forever and it should be ok. I never had problems with my rx1 but I know I have read about other people who had fouling issues.

Could I run the cr8ek will it hurt it at all

I wouldn't. Probably burn a hole in the pistons.

IT s no problem running 10 they give you a coupel more HP go to ulmers page and look them up.
Run them in my 03,06 and now in my new apex.
The only problem is if you dont let the engine get up in temperatur you flood the engine.

Can I ask how do u get a coupel more hp out of a colder plug

I have only started and let idle. seems to start a little quicker. Only reason I installed is cause I have read a few threads stating these will gain 2-3 HP. We will see.
