2006年9月17日 · Just about everything is new: cap, rotor, magnecor wires, those RN9YC plugs, the engine was rebuilt out of Oregon by British Auto Works. I bridged the HT lead with a screwdriver to #1 cylinder and she backfired. I pulled the dizzy and spun it 180, still no go. Neither the old plugs nor the new are doing jack.

2006年2月11日 · The only difference between a Champion N9YC and RN9YC, is that the RN9YC has a resistor built into it (hence the R) to eliminate interference with the radio and other electronics.

2016年5月5日 · I went to the parts store and asked for the same plugs (unknowingly). They could not find those and suggested something else. I got home and pulled the old plugs and noticed a slight difference in length so I looked online and saw the RN9YC was the correct plug. I …

2006年9月18日 · The guy at Kragen told me these were essentially the same spark plugs, but I just cannot get this engine to fire. I have it set to TDC with the timing marks lined up dead on. I have a pertronix/flamethrower set up with my 25D. Coil is getting power and fuel is in the carbs(HS-4). Plugs are wet with

2016年12月9日 · Hi Guys, After having an go around with the car being 180* out for over 100,000 miles running Champion Iridium plugs and finally getting my Schlemmerized dizzy to work, all was well until: 1) one of the Taylor Pro silicone 8mm HT wires crapped out and then: o 2) the 2 coils

2006年1月24日 · Bugeye needs sparkplugs, and I am sure this is a simple thing that is making me crazy. I haven't been able to find a modern replacement plug for the manual Champion N5 original plug. Is the RN9YC or RN5C a good replacement? Edited 1 time(s).

2016年5月5日 · according to champion the only difference in them is the hex size but compare them to make sure check the length if the electrode and thread length to be sure one is not longer the length from above the hex to wire the wire goes on does not really matter since it is out side the engine the length below does too long and you risk it …

2019年7月25日 · Just a poll to see what everyone is using for plugs in their 'B'. If you wish to respond, please indicate whether you are running a standard engine or with modifications and what gap you set them at. I've always used Champion RN9YC, but …

2024年1月6日 · I've put hundreds of thousands of miles on both Champion and NGK plugs. Never had a problem with either. For some people it's a Chevy vs. Ford thing, they just have a preference and won't use (or say anything nice about) anything else. I've used both N9YC an RN9YC in a few engines. Very good plugs.

2010年6月24日 · I have a 1979 MGB and it would appear that the Champion RN9YC is the recommended spark of choice. I live in San Diego so it is a warm climate and it is also my understanding that the NGK's are good but run hotter. Any thoughts as to what I should use? Thanks, Scot Edited 1 time(s).
