Other than price can someone tell me the difference between a 5422 and a 3961? Amazon says the 5422 will not fit my Polaris. When I have bought at Auto Zone I just told them I needed a 8BRES.

The 3961 has a solid terminal where the 5422 has the removable nut kind. Looks like the solid terminal is larger in diameter.

Quote:

Plugs with a solid terminal nut can only be used with the larger, snap-on connector type. The terminal is part of the plugs design and cannot be removed. Most automobiles utilize this type of connection system.

In cases of high vibration, a removable terminal nut may become loose and create an insecure electrical connection. Therefore if a terminal nut is used on marine, ATV, or similar applications, the selection of a plug featuring a solid terminal is preferable, if available.

Ok, thanks. Solid terminal is double the price. I have some of the removeable ones and never had a problem.

I never had issues with removable ones on the multiple dirt bikes I've run.
