Yes they are the CR9EKB plugs and I got them at my local dealer. It is the same plug that is used in the Phazer sleds. That plus putting Amsoil 0w-40 in after the break in miles is the only thing that has been done. I do have the marginal snow wheel kit and that has cut down on some friction but I had those on last season so that can not be considered in the way it performed this season. I noticed better throttle response right away with the CR9EKB plugs and after getting out on the trails it just flat out rips.yamyfreak said:

Freddie Klies of ECP did the testing of the NGK10 dual electrode spark plugs back in 2004. All of this testing was done on an 03 RX-1 onthe ECP dynamometer. He reported 2-3 HP increase and offered these plugs aspart of his ECP air intake kit. As far as I know, the NGK10 dual electrode plugs were not tested in the newer fuel injected engines.
