        Just what I needed

        I noticed some rough idle (but no codes) and I decided it must be the plugs. I had installled some NKG 0-degree plugs but thought I didn’t need to gap. When I pulled them they were at .030”. These came in with no damage, but all gaps were out of spec for my ‘09. (.040” rather than .052” - .056” according to AM) Once installed my idle improved significantly.

        OEM correct

        My 09 is modified just short of forced induction so I stayed with OEM replacements. They're exactly the same as original. Something I found odd was it said on the box that they are not gappable. What? Why not? They're just spark plugs. They were pre-gapped at just .035. So after chatting with AM tech, I gapped them anyway. All is good. At 66,000 miles it needed them. Taking my time following AM instructions it would have taken about 2 hours but the porcelain on one of the old ones cracked and that doubled the time running to the store to get some tools to clear the porcelain bits from the hole before removal.

        Do what they're supposed to.

        Direct motorcraft replacement. High quality as always. Just rolled over a hundred thousand so I swapped my plugs and my car is now running perfectly. Thanks AM

        Perfect OEM Replacement

        Changed mine out at a little over 30,000 miles on my 2009 GT, perfect fit and no issues. Only took me about 2 hours, and much of that was spent waiting on the lubricants to soak in.

        1 2010 GT - ICEE Installation Time: Afternoon

        Not a great buy

        I installed these on my 2010 GT and had cylinder #5 misfire then after checking the spark plug I noticed the white ceramic part was cracked, replaced with a new one from the store and had two more spark plugs crack after that as well, the quality of this product was not what I expected, took all of them out and placed my old ones back in, no problems.

        Great pricing

        For some reason no local parts store carried OEM plugs for my 08 GT. One store had NGK had $27 per plug. Great pricing and AM has the best customer service ever.
