The 17 is a colder plug with a heat range of 7. The 19 is hotter with heat range of 9. The higher heat range is preferable for colder climates. While the 17 is for warmer areas.
The "R" just designates a resistor plug. You are fine with the J19LM.
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.
The J19LM and QJ19LM are Champion brand spark plugs used for garden machinery. The difference between them is their resistors, the J19LM use a regular resistor while the QJ19LM uses a CDI resistor.
yes
Rj19lm
Yes, If a spark plug with a different part number fulfills the requirements of the engine, can be replaced.
Champion J19LM or RJ19LM
Champion J19LM
torch GL4RC or Champion J19LM
Rj19lm or j19lm
The Champion spark plug rj19lmc should be able to replace j19lm. Many of Champions spark plugs are interchangeable with plugs with the same letter coding.
on the back of the plug package it has : replaces CJ8, RCJ8, J19LM & RJ19LM. hope this helps.
