Methfireroad Posted April 28, 2013 Author Report Share Posted April 28, 2013 I'm pretty sure they are CEL. And I'm running the the b9 because my builder said I should run them and they r a cooler plug. Wanted to see if some other people where in the same range Quote Link to comment Share on other sites More sharing options...
