However, contaminate the plug with fuel (even just a little) and a high value resistor will cause the plug not to fire. Who is the longest reigning WWE Champion of all time? You currently have javascript disabled. The plugs I have are cheap (Napa) but they seem to be working. (the downs) as mentioned before the less resistance the better the current,being that the resistor plug has resistance it will make the current run slower;to which it will have less performance than the none resistor plug. I think you just happened to pick a short non resistor and long resistor part. Positively no issues with using non resistor caps. NGK resistor caps are designed to give perfect noise suppression across all frequencies whilst engine performance is not adversely affected whatsoever. 1971 Moto-ski Zephyr. Am guessing that Kawasaki fitted the oem resistor caps in order to reduce RFI (radio frequency interference), and … 1972 Nordic 640 ER The non resisted caps have part numbers such as LZFH & R90 which are right angled with different fittings for SAE (this is known as a bullet fitting on top of the spark plug). Thanks everyone for the responses. Several functions may not work. Re: Resistor Vs, Non Resistor Plug with MSD Post by Dodge Freak » Fri May 24, 2013 10:01 pm Its better to run too cold of a plug, then too hot of one and with pump fuel, all the more so. the difference between resistor,and none resistor spark plugs?the none resistor plug-(the perks) the none resistor plug has the better overall performance,because when it come to electrical current:the less resistance the better current.

NGK have by far, the largest range of plug caps and most are resisted. Am I going to burn up the plugs, or the generator/magneto? Agreed, the length is independent of being a resistor plug. Why don't libraries smell like bookstores? This is not recommended for shared computers, Community Forum Software by IP.Board 3.4.8. Should I be concerned about running non-resistor? Most caps that we stock are new, as the old stock is becoming increasingly hard to obtain. NGK Resistor Caps. The difference between them is their resistors, the J19LM use a regular resistor while the QJ19LM uses a CDI resistor. You should use resistor type spark plugs with an EFI system, to suppress electrical noise/interference. They keep popping off, which of course, leads to power issues. NGK strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. A suppressor can take the form of a discrete resistor in the sparking plug cap, an in-line fitting in the HT cable, a discrete resistor in the sparking plug itself, or by the conductor in the HT cable being resistive. I am trying to find NGK caps that will work and they have so many options on their website it is crazy. (the conclusion) if your going to have a car/truck etc performing in such as a race,then go for the none resistor plug,but if your using a car/truck etc for everyday commuting,then go for the resistor plug.GOOD LUCK,AND GOD BLESS. Use of a non-OE resistor type could result in engine damage and end plug life. My 05 PX150 came with the standard, primitive spark plug clip and a resistor plug. This type of resistor creates around 40ohms of physical resistance, compared to the 1000-5000ohms of resistance in typical monolithic resistor plugs. 1971 Elan 250 They feature a resistor element pressed in between the spark plug cover terminal and the high-tension connection (HT lead).

The J19LM and QJ19LM are Champion brand spark plugs used for garden machinery. When did organ music become associated with baseball? They will turn on their panel indicator lights, wiggle their gauges around, and do other strange things if connectivity to the resistors is faulty, or if non-resistor spark plugs are installed in them. Hmmm, 5 wrong answers, until this post. Rode it a bunch this morning/afternoon. Resistor type spark plugs typically include an "R" in the part number for ease of identification. They keep popping off, which of course, leads to power issues. NGK resistor spark plugs contain a single ceramic monolythic resistor of … Ultralight Engine Info should have their resistor spark plug caps checked for continuity with an ohmmeter, periodically, as they are prone to corrode inside from the elements, especially if the engine is run inverted. 1975 Elan 250 As the resistor spark plug has an incorporated resistor, some people think that it has adverse effects on start-up, acceleration, fuel economy and emissions. NGK "R" or resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking. NGK resistor spark plugs contain a single ceramic monolythic resistor of approximately 5000 ohms. (Unless it's a race only application and the non-resistor plug is the only heat range & dimensions available.) However, this is wrong. I've looked at 5 or 6 places here in Richmond and can't find one (they sell for about $2 online, but I'm too cheap to pay $6-10 shipping on a $2 plug). Older Vehicle Maintenance Issues Just got a new set of Dynatek (solid core) wires DW200 which came with the wrong crimp-on ends to attach at the coils. Resistor spark plugs should always be fitted, therefore, where specified. What are some samples of opening remarks for a Christmas party?

How long will the footprints on the moon last? You could look around with the guys that have lots of NOS stuff part# 420 983 409 (Ski-Doo part#) if your looking for originals. However, if you do want to use resistor caps I wouldn't use over 1 K ohm resistance with the point system to keep the spark as strong as possible. Some time ago I swapped out the clip for an NGK 5K ohm terminal stud cap and switched to non-resistor plugs because they were easier to find. Any suggestions on the proper part # for NGK? I would like to find some that look similar(red) to the originals. My Craftsman 42cc engine specifies a Champion RCJ-7Y spark plug. Since resistor type plugs actually “resist” some of the spark energy, non-resistor type plugs actually deliver a more powerful spark. I have been running solid core wires with non-resistor caps, and BR8EIX (resistor) iridium spark plugs. Spark ignition is resistive sensitive. The NGK range of resistor caps provide the perfect connection between your high tension lead and spark plug.
