safetyguy Posted September 20, 2008 Share #1 Posted September 20, 2008 (edited) Anyone have any experience using a Champion RA6HC plug vs. the NGK DPR8EA-9? What about the Autolite 4163? This is for my 88 VR? Edited September 20, 2008 by safetyguy typo Link to comment Share on other sites More sharing options...
GeorgeS Posted September 20, 2008 Share #2 Posted September 20, 2008 Most members agree, the NGK, stock number plug is the best. I would just stay with the NGK's. Link to comment Share on other sites More sharing options...
BOO Posted September 20, 2008 Share #3 Posted September 20, 2008 I usually use the NGK plugs but I think the ones in the bike now are Champion. I can't seem to tell much difference in them but the guy I ride with quite a lot is an auto mechanic and for some reason he don't care much for the Champion plugs. He also don't like the fram filters but I get good results with them. Just my opinion. Jerry Link to comment Share on other sites More sharing options...
Squidley Posted September 21, 2008 Share #4 Posted September 21, 2008 NGK's.....I have never had good luck with Champions, keep the stock plug in it. Link to comment Share on other sites More sharing options...
Yammer Dan Posted September 21, 2008 Share #5 Posted September 21, 2008 I've used a lot of the Autolite 4163's. Don't cost a bunch to replace them often and seem to work as well as any. Link to comment Share on other sites More sharing options...
oldandcrotchety Posted September 21, 2008 Share #6 Posted September 21, 2008 I've used both NGK and Autolite and can't tell the difference. I quit using Champions years ago because the porcelain was so fragile that I would almost always break one every tune up while trying to tighten them down. On a V-8 I would usually buy 10 just so I wouldn't have to go back to town and buy another one or two. At the time I didn't think it was just Champions since that was about all I bought. Then one day someone told me to try AC or Autolite and I did. Never broke another plug and never bought another Champion. I've been told that they aren't like that any more, but I'm out of the habit of buying them now, so i don't know. Link to comment Share on other sites More sharing options...
Venturous Randy Posted September 21, 2008 Share #7 Posted September 21, 2008 I have had good success with Autolites for years. Advance Auto sells the ones for the Venture and they are real cheap. These older bikes seem sensitive to clean plugs and if you had a carb problem, make sure you change your plugs. RandyA Link to comment Share on other sites More sharing options...
safetyguy Posted September 21, 2008 Author Share #8 Posted September 21, 2008 I'll stick to NGKs for now but maybe next time I'll try the Autolite ones. I have had bad experience with Champions over the years too. Thanks for everyone's input -- I'm glad this didn't turn into a "which oil is better-type" thread.

PEIslander Posted September 22, 2008 Share #9 Posted September 22, 2008 I put NGK's in mine the first year I owned it but in the fall they fouled up quickly when I had to use the choke. Up here the NGK's cost about $5 each. I replaced them with Autolites I got at a Farm and Fleet in Milwaukee for a buck each and they have been in for 2 years now. with about 10,000 miles on them. I'll probably replace them next spring. Like the others said I haven't had good luck with Champions and usually stay away from them. Rick Link to comment Share on other sites More sharing options...
Gearhead Posted September 23, 2008 Share #10 Posted September 23, 2008 I've only replaced the plugs in my 87 VR once, replaced NGK's that looked not bad really, with new NGK's just because. They were only 2 bucks a pop at Pep Boys, not too bad. But I will express a little different opinion; I've run Champs in my Virago for years simply because they were only a buck apiece at Pep Boys. (Yeah, there are only two of them in a Virago, but I used to be even cheaper than I am now.) I ran them a long time, 20k miles plus on a set, and they were fine. Frankly, I've never noticed any difference switching plug brands in anything. Jeremy Link to comment Share on other sites More sharing options...
bobcat Posted September 23, 2008 Share #11 Posted September 23, 2008 I've had no problems with the NGK's non-resistor plugs on my 86VR...It seems the non resistors run better longer... Link to comment Share on other sites More sharing options...
Gearhead Posted September 23, 2008 Share #12 Posted September 23, 2008 What about extra noise in your radio and audio system? Jeremy Link to comment Share on other sites More sharing options...
SilvrT Posted September 23, 2008 Share #13 Posted September 23, 2008 I've been using NGK's for years and have been using the Irridium ones for about 5 or 6 years. I've had my '87 for 3 summers now with same irridium plugs. I too stopped using champion plugs many years ago...they never seemed to stand up and yep, I found they broke easy.

Saddle_Bag Posted September 25, 2008 Share #16 Posted September 25, 2008 I have used Autolite and Champion. My 84 currently has Champion. Champion has improved, I blew them off a long time ago myself but out of necessity tried a set several years ago. I think the new numbering is 908??? I don't know why they feel like they need to change numbers. This plug has what they called a fine wire electrod. I have had them in the bike for 3000 miles and when I pulled them they looked like the day I put them in. The base nut is 5/8th, which make removal much easier than finding the thin walled 18mm. Only problem is that you need to blow out the plug area before you remove the plug so dirt don't fall in the hole when you remeove the plug, then again you need to do it with NGK and Autolite.; I paid less than 2 bucks a plug. joe Link to comment Share on other sites More sharing options...
BamaVenture06 Posted September 25, 2008 Share #17 Posted September 25, 2008 3 mechanics have all told me the same exact thing: Use NGK plugs. Second choice: Autolite And all 3 said never use Bosch or SplitFire cause they are crappy. Link to comment Share on other sites More sharing options...
Saddle_Bag Posted September 26, 2008 Share #18 Posted September 26, 2008 I'll go along with crappy splitfires. I have two sets in the garage that I removed after installing them. After complaining, I was talked into another set, just in case I got a bad set. Sometimes we all do stupid things. Crappy is a good word for expensive trash. joe Link to comment Share on other sites More sharing options...
greg_in_london Posted September 27, 2008 Share #19 Posted September 27, 2008 I hate to be unpatriotic - and also to rely on twenty year old anecdotal evidence - but with Champions it was always necessary to be ready for a duff spark plug, maybe to be ready to have a spare to replace a bad one. Why change out old NGK ones for Champions for ones that might not work - generally as a way of eliminating possible problem components to diagnose a problem you don't want to add questionable parts. I never had a bad NGK plug, so I've never gone back. A couple of years ago Champion were promoting copper cored plugs. Whoopee do. Link to comment Share on other sites More sharing options...

a1bummer Posted September 28, 2008 Share #21 Posted September 28, 2008 Stay away from Champion plugs. And by all means stay away from any fancy plugs with multiple or split ground electrodes. I've seen far to many holes burnt through pistons and many other costly problems due to them. Link to comment Share on other sites More sharing options...
lonestarmedic Posted September 29, 2008 Share #22 Posted September 29, 2008 Ditto on Champions. I had a set of the new copper cores when they 1st came out. I put them in my 1982 Gold Wing. Took them out on the side of the road and put the NGKs back in. The Champions were not burning hot enough. Seemed to cut out some of the strength of the spark. I use plain NGKs. Don't trust the super fancy ground electrodes. Can say that Autolite has never let me down. I run NGKs in my 4 wheel vehicles. JB Link to comment Share on other sites More sharing options...
