More Spark Plugs (4.3 Cobra)

[Grouchybear35]

Hello All,<br /> I sent my heads out to be done for my Cobra 4.3 and they came back plugless. I have no idea what was in there however I think they where AC plugs. Can someone tell me what I should be running? This would be greatly appreciated. Also,<br />The gasket set that I got had the wrong exhaust gaskets in it. Can some one point me to a good place to order these.

If there is a carb on this 4.3 Cobra engine. AC MR43T OR NGK BR6FS. Sierra offers exhaust gaskets for that engine.

Is this the same on all model years of the 4.3. I have a 1989 OMC cobra 4.3 liter would the same plugs apply???
Thanks For Any Help

yep.....it will for your 89...use the AC plugs...NGK has never performed as well for me as the AC plugs do.

Rock auto.com has the AC MR43T plugs for about 1.60 each.

Ebasicpower.com has the gaskets if you can't find them here on Iboats...
