🔥 High-Performance MAS Ignition Coils DG511 GD511 FD508 + Motorcraft Spark Plugs SP546 PZH14F Bundle - Compatible with Ford Lincoln F150 2005-2008 (8-Pack, SP515 Compatible) Review

Have never had a problem shopping at Revain before. You are so weak and old. 3 spark plugs broke and did not fire for 12 hours. The coils are broken.

Delivery was fast! Put them on a 2004 f150 4x4 and they've done about 800 miles with no problems. If you're having intermittent misfires or stuttering, this is what you need.

I had a misfire situation in my Ford SportTrac and various forums suggested that the ignition coils were the likely culprit. The dealer wanted many hundreds of dollars for a full set of coils so I decided to try these which were several times cheaper than the dealer price. I was a little skeptical but have just driven 5,000 miles with these rollers towing our caravan with no problems. Happy tourist. Literally.

Far less than Motocraft's price for reels. I installed about 10 days ago. Just drove into the mountains, 300 miles, 20mpg on my expedition, so far so good. I'll post again when I can, and if I run into any issues, 5 stars if Ford OEM. And buy a SmartGuard protection plan, I had it before but never had to use it so we'll see. To update! Don't buy these reels, buy Motocraft

I installed coil packs because I had misfires in cylinder 4. I changed the spark plugs a few weeks ago but I used my old coil packs. My car ran fine until it misfired on cylinder 4. I used these coil packs and have had several misfires since installing them. I have contacted the seller and they are sending new ones, I hope they work. Will update when I get it and install it, but I won't be buying from this company again for now! update ahead.

I had sporadic misfires on cylinder 1 and cylinder 5. I knew the spark plugs were old and the coil packs on my Triton 3v were never changed. I bought a 9/16" magnetic spark plug socket with a Triton 3v spark plug extender and installed it immediately. Works great, no codes or misfires! Those are also real 546 candles, not 515! This is a one piece fork, not a welded fork which is notorious for breaking heads! Would definitely buy again!

I had problems with the performance, it seemed like there wasn't enough power or the gearbox was slipping. I used this kit to replace all the spark plugs and coils and now the problem is completely gone! Great price, I would buy again. Note: Apparently the spark plugs in these engines have a tendency to crack when you try to remove them. I had 1 out of 8 breaks which is really good according to the Ford mechanic I spoke to. I ordered a Lisle 65700 blown spark plug removal kit for a Ford 3V…

Ordered there due to normal terrible shake 5.4, knew better to run coils so I just ordered them to use rubber boots. Anyway, I installed spark plugs which are supposed to be the latest design 5.4 3V to replace the SP 515 but since installing them my truck has not even been able to pull out of the driveway. I replaced the spark plugs with a cheap Autolite to see if they were spark plugs after changing 2 sets of coils and all but 1 of the spark plugs were bad. The top that snaps into the spring…
