Champion RJ19LMC. Gap 0.020. Make sure it has the "C" on the end. The two are very different.
Champion RZ7C
Denso W14P-U, NGK R5670, or NGK 2298 If you mean a Champion J13Y then the equivilent is a Champion RJ14YC, NGK BP5S OR Motorcraft/Autolite A52. If your in doubt then go to the Champion website and do a search for J13Y and it will show the current Champion equivilent of RJ14YC and if you do a google search for Champion NGK conversion then you will find several sites that will show you both a Champion J13Y and RJ14YC both convert to a NGK BP5S.
Chrysler has used both Champion and NGK as original equipment.Chrysler has used both Champion and NGK as original equipment.
The replacement plug for Champion RJ2YLE would be B&S 799876. This spark plug should have a gap of .020. This type of plug should not be used though with Quantum series 625, 675 and 725 or any L-head engine.
The NGK BR8ES seems to be listed as an equivelant. See http://www.sparkplugs.co.uk/pages/technical/Champion-to-NGK-cross-ref.htm
I have autolite sparks plugs ARF32M and need to know the cross reference to NGK
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.
