COPPER SPARK PLUG GASKET M674 (PACK OF 100)

Copper gasket. It always works as it should.

Got them. Thanks.

Exactly as described...👍

They were reasonably priced, shipped and received promptly, were the right size. I didn’t count them, but no reason to think there were less than 100. Which should last me quite a long time - using them on a classic car with 2 plugs for each of it’s 6 enormous cylinders.

Exactly as advertised!

Buy 100 of the spark plug gaskets and you will not find a better price on new gaskets.

They are round, which is good, and they fit my spark plugs, which is also good.

great value. The best price we could find.

Good price and work as expected.

was just what I needed

Heres the deal folks...All aircraft engine manufacturers specify using a NEW gaskets when removing and replacing aviation spark plugs. If you run a Repair Station or you are an A.I. you best be using NEW gaskets (and billed on your work orders) to avoid potential liability issues. These generic branded M-674 gaskets are the correct Rockwell hardness and dimensions. We use thousands of gaskets per year and these Aircraft Spruce gaskets are now our #1 choice.

Look just like OEM. More convenient than buying a box of 100.

no complains

circular and flat, good stuff

I just watched a video on youtube of a fellow taking old gaskets and heating them with a blow torch to anneal them, so he could reuse them....even though they were crushed and had a raised lip. I like the idea of reusing things, but when a brand new copper gasket costs about 36 cents, that seems pretty stupid. Buy a handful of gaskets and let them sit in your tool box, and use them anytime you take a plug out... Good product, very low price.

excellent on time shipping

Excellent

Nice

as expected

This spark plug gasket is exceptionally round where it needs to be and flat in other places. It is also coppery.

The spark plug gaskets were really round and... coppery

Good price

They are very shiny, I like them a lot.

work as advertised

good fit, worked well.

Works Perfectly.

excellent value! works well.

Brand new washers as expected. Very inexpensive and despite the old wives tales of just annealing old ones to save money brand new is the only way to go.

Seem like nice washers! I recommend these!

I bought these in preparation for installing all new Champion plugs. Guess what? Each of the new plugs is packaged with a gasket so I didnt need them. Ill keep them around anyway for the next time the plugs are cleaned and gapped.

delivered as ordered, excellent service

We use 500-1000 gaskets a month. The quality control is excellent.

perfect replacement , good looking product worked as advertised.

Proper fit and finish, good value.

perfect replacement when reusing sparkplugs

Good package of spares. Easy to find and add to order.

Great value, but I miss the box. Perhaps they could be packaged in a ziplock?

It took a little longer than I thought but good service, after a call with a courteous person that made things happen. No question I will be back..

50% of the washers I ordered came completely warped
