Q: I have Champion REM38E spark plugs. Do I use 18MM or 16MM gaskets?

You will need to use 18mm gaskets for REM38E plugs.

Q: What's the difference in these and the M674 champion 18mm?

The only difference between the two is that one is made by Tempest and the other is by Champion.

Q: I have Tempest fine wire UREM38S XL spark plugs. What copper gasket Tempest part # do I need? Also, is there an alternative vendor part#?

These are the correct copper gaskets for your plug. Our part # is 07-01798, Tempest manufacturing part # is UM674PK.

Q: I have Tempest URHB32E spark plugs. What is the right gasket to replace the original gaskets?

URHB32E uses 18mm gaskets. So you can order this part # 07-01798, which is a 100 pack, or you can order part # 07-00877, which are sold individually.

Q: Does Tempest plug UREM40E use an 18MM gasket?

Yes.

Q: I use RHB32E Champion spark Plugs. Do they take these 18mm gaskets?

Yes, the B in RHB32E designates 18mm. These will work on RHB32E Champion plugs.

Q: I have UREM38S and UREM37BY. What size gasket and part number do I need?

Both the UREM38S and the UREM37BY are 18mm spark plugs. This part # 07-01798, is the correct size for these plugs.

Q: Is this 18mm gasket (M674) the correct size for a Tempest UREM38E spark plug?

Yes, it is.
