if your looking for a good plug use the ngk iridium, thats all i use. champ is garbage. autolite will work. denso is almost the same as ngk iridiums, just pay more for denso. splitfire good for your lawnmower! splitfire has 3 points to cross no good. just remember the DCPR7EIX does not fit for all bikes. check your specs. hd stock plugs last about 3800 miles if your lucky. but you have to choose your self. burn them up till ya find the right ones.

 

Seem like it would be easier if you could put in the vehicle information and then display all of the available plugs.

 

Denso iridium for an '07 FLHT 96CI?

 

So far, the site sucks for buying marts for a bike! They give you a way to search for makes of cars, makes of plugs, or by part number, but as to searching by motor type.... CRAP!
