I have had good service from Autolites, also. However, Autolite has been shifting production to China, so look at the box, to see where the plugs were made. I would use made in USA, maybe made in Mexico, but never made in China.

Champions were made in the U.S.A but last year I discovered they were now made in Mexico (from the previous year). I even sent them a letter letting them know I expected a price decrease since their labor cost was now lower...no response.

Great question cause our builds are so very similar,I do want to push mine closer to 12.5 but the plugs probably should bee the same.On kinda the same subject what is recomended for a 10.7 motor?Guzzi Mark

I use NGK V-powers in my stuff. GR5 is 2 heat ranges colder than the stock recommended GR4. Heat range is reversed --> higher number = colder. I run GR4 or GR45 in my current engines.

I'm no expert, and have never had anything over 11:1, just my 2 cents.

I run RN9YC OLD CHAMPION # .Cross to your favorite brand.
I have the Race Hemi plug # at the shop .Not sure of the Brand but for a 14 to 1 engine. I will get that for you for comparison.

The Champion race plug # N59YDR or #N61YDR

cool. Thanks for the info.


I Will be going with NGK - I really like them and I have do do a bit of research on them but I can probably get it fired on some old plugs from the dart for now.

I use the Champion # because I had a chart. FYI I had thought about the new E3 plugs so I looked them up and they use the same plug # for all the heat ranges From N9Y to N17Y. So I questioned them on how could this be in their Tech Forum and got no responce. Guess they don't really want to sell sparkplugs.

Gimmicky trash from China. It's all sizzle, no steak. All hat, no cowboy. All litterbox, no cat.

Yes Guys I dis use some of those Champions in the dart a while Back.

I have been doing a lot of research on spark plugs.com,

I have a finewire irridium NGK heat range 9 in the dart from over the summer. ET's went down. .06 Seconds and Picked up 4mpg using thsis plug vs other stuff.



I got some NGK fine wires for the Ruster Engine too. Just one heat range colder NGK 10 - Should be good - We'll see.


I can supply Part / stock #s if anyone cares.
