Pack of 8 Genuine Motorcraft Spark Plug SP-493 AGSF32PM

Works as they should.

I just removed what I presume was the factory original identical plugs from my (new to me, used) 100,000 mile 4.6L 2005 Merc. Grand Marquis (same as the Ford Crown Vic, Lincoln Town Car). No records of plugs having been done, and idle started getting slightly rough. Figured plugs were among the items needing attention. These are a steal at $3 per platinum plug. By comparison, my 6.4L Challenger Hemi requires 16 plugs (2 per cylinder, 8 cylinder car) and those plugs are around $15 each. Anyway, installation on the 4.6L is low skill but requires a healthy dose of patience and a extensive socket set with elbows, extensions, and many fittings. Plan on a 4 hour job if you're not an expert, and watch a few videos for tips. I just finished and took it for a test drive and it purrs like new, no more rough idle. It feels pretty good doing a maintenance job that will last another 90,000 miles (the recommended period to replace plugs). These plugs are fantastic and a bargain price. I'm buying another set to put in my extra parts box.

Great product, even better price. would buy again. made my 4.6 run like a brand new engine.

Genuine Motorcraft Spark Plugs . Could not get these for my Mustang in New Zealand so was happy to find on Amazon, arrived on time and they performed as expected and fixed my misfire.

These were great until I ran out of oil and seized the engine. I'm a shade tree mechanic so I felt super dumb, because I was trusting the oil gauge, which had malfunctioned. They won't prevent your own stupidity from destroying your engine, but why would they?

Arrived quickly and were pre-gapped well. I checked anyway. Installed today on my 2004 F-150 4.6L.

Always like oem in Ford. I own several Ford trucks.. I have tried several different types of plugs back in the day, not getting the power or fuel mileage I wanted. I went back to the original plugs, what the owners manual shows for the vehicle. If the factorys that builds Ford , mercury, and Lincoln puts motorcraft spark plugs in they have to be the right one. Most of my trucks use the platinum plugs on average I get 80 to 100 thousand miles between changing. Motorcraft quality and performance along with very competitive price ( usually a little cheaper). I've learned u can't go wrong, so look in the manual for the right ones to fit your vehicle.
