Yes, If a spark plug with a different part number fulfills the requirements of the engine, can be replaced.
Yes. Or a 5861 which is the plug number to replace RJ19LM, J19LM, RJ17LM, J17LM, RJ19LMC, RJ2YLE, 799876, or RJ2YXLE, SOURCE- I work at Pepboys and it says directly on the package.
My book for my John Deere snowblower , which has a 5 horsepower Tecumseh engine , shows to use the Champion RJ17LM spark plug
The correct spark plug for a 5 hp. Tecumsen 4-cycle motor is Champion J-8 (RJ17LM). The plug gap is 0.030 in. (0.76 mm)
Yes, a Champion J19LM spark plug can generally be used in place of a J17LM, as it has a similar design and thread specifications. However, the J19LM has a slightly higher heat range, which may affect engine performance in certain applications. It’s essential to check the manufacturer’s recommendations for your specific engine to ensure compatibility and optimal performance. Always consult your vehicle’s manual or a professional if in doubt.
No!
You have to remove the Coil on Plug modules from the intake, and then use a long extention to reach to spark plugs deep in the intake manifold. Instead of having spark plug wires going to the tops of each spark plug, the system has a separate ingnition coil attached to each spark plug instead. Just a little more involved than older cars.
Yes you can. The "R" simply refers to the plug being a resistor plug. The size, diameter, heat range and thread pitch are exactly the same.
No there is not a single spark plug coil wire like on the earlier vehicles. Instead, if you have the 5.4L you will find eight coil packs one on each spark plug. In addition, if you have the 4.6L you will find two coil pack blocks.
A Coil On Plug ignition system has a coil for each spark plug ( the 5.4 L has always been Coil On Plug - C.O.P. ) the newer 4.6 L are now Coil On Plug instead of having 2 coil packs - each coil pack handling 4 engine cylinders / spark plugs and using spark plug wires
If you mean that the wire came out of the boot, then pull the boot off of the spark plug and use a spark plug socket to remove the spark plug.
The correct spark plug gap does not depend on which plug you use, it is dependant on what engine it is installed in. The same plug can be used in many different engines, and each engine might have a different gap specification. Instead, you need to ask something like: What is the correct spark plug gap for a 1993 Chevy 350 engine? (or whatever engine you have).
Spark plug wire not connected to spark plug? Spark plug wire connected to Wrong spark plug? Vacuum line disconnected? Bad spark plug or wire?
