🔥 Enhanced Motorcraft SP-411 Spark Plug for Optimal Performance Review

3 out of 6 did not have the same number and did not fit. Unfortunately I installed before realizing that they ship 3 different ones (they were a bit shorter). Had to be removed and then driven to the Ford dealer to get the other 3.

Because Ford plays an important role in the production of Mazda cars, you can often see FoMoCo branded parts in the engine bay if you look closely. Original equipment, accelerates smoothly, without dropouts. Just remember to set the clearance to 0.030 for the Mazdaspeed 3/6/CX7 MZR 2.3 turbocharged engines and you should have no problem.

The plugs I received certainly didn't look new. I compared the spark plugs to some new AutoZone spark plugs and the spark plugs I ordered online looked used. Because of the work involved in getting to some of the ports on my computer and the way those ports looked when I got them, I didn't risk using them. Bought a new set. I would not recommend these forks based on what I received.

Price sounds too good to be true. I ordered two packs. I installed the plugs and the car sounded like it wouldn't work. I've been troubleshooting all weekend trying to diagnose the problem. But no luck. I ended up putting the 3 old spark plugs back in and the car ran normally again. After inspecting the candles, I noticed that some of the needles were off center. Is it defective spark plugs? Is that why they are so cheap? At least not happy.

Ordered these for my Taurus, replaced and the machine runs like new. Exactly what I expected from a Motorcraft part. However, be sure to check the manufacturer's part number on the box. Revain put the wrong label on the box and I got four wrong corks. The Revain label said SP-411, but the label on the box said SP-417. Be sure to check your parts before disassembling the machine! Aside from that *minor* issue, Revain was great and I was able to return the wrong plugs.
