I just switched from the Harley Davidson plugs (which probably cost $12 bucks a piece) to NGK plugs. I know they have a great reputation in many powersports vehicles. Has anyone else used them?
If not what do you use in your sporty?

 

I have only used the factory champion ones. Not a problem with them.

 

I just run the old reliable $2.50,Champion RA8HC.

 

I use the NGK plugs on mine.

 

NGK DCPR7EIX Iridium.Stock ones only lasted 20,000 kms.

 

Champion RA8HC here. It's the same plug as from the factory, just without the $10 Harley-Davidson printed on the side of the plug.

 

Like WRAITH, NGK DCPR7EIX Iridium's in my 1200.

 

I only paid $2 apiece for my Harley plugs, where do you get this $10 ****?

 

The dealership here wants $15 for the harley ones.....I get the champion ones for $1.42....talk about markup!! lol

I can't see spending more money for the latest 'whiz bang' sparkplugs when it's not needed.

I've used Champion and standard HD plugs in my bikes, under all kinds of conditions, for years and years and years, without any kind of problem.....

The Champion RA8HC works just as well as the HD 6R12, which isn't surprising as the last I heard Champion was still making the plugs for Harley.

I change plugs around the 8,000 to 10,000 mark, or whenever I happen to think about it. For all you that believe in going strictly by Harley recommendedschedules, I'm pretty sure they say to change out the plugs every 10,000 (or as needed).

What's the price of 2 Champion RA8HC plugs, maybe $4.50? Guess if you need to spend 'big bucks' you could get a couple of HD6R12 plugs for $9.00. Less than the price of a meal or a few beers.

But if it makes you feel better to spend more money for the latest'super plugs' be my guest. I'd rather spend my money on something that actually makes a difference.
