🚗 CarBole 8 Pack Curved Boot Ignition Coils, 15% More Energy for Ford F-150 F-250 F-350 4.6L 5.4L V8 Crown Victoria Expedition Mercury Mustang Lincoln - Compatible with DG508 DG457 FD503 (8pcs, Yellow) Review

My V-10 F-250 is purring like a kitten again. I bought a 10 pack for about the price of 1 Motorcraft reel. Immediately needed 2. 8 are on standby. 2 of these are kept on board in case of an off-site failure. The truck "lives" in the Mojave Desert. The heat and cold here will be a good test of strength. Ask me again in a year and I'll provide an update.

Installed on my 03 F-250 V-10 And it came back to life like new. I like that there are no more hesitations or delays. The only thing that sucked when installing it was the rear passenger side, besides being a breeze to install. I've only had them for about 5,000km but they still work great. so i am happy with my purchase.

I used them on my 2001 Ford Crown Victoria. So far they're working great! My car was idling and very sluggish. These ignition coils really woke up my engine. Significantly improved throttle response and smooth idle. (UPDATE 6/17/19) One of them (#3) stopped working today! Some people seem to have a bit of luck with this, some don't. My advice: if you're short on money, buy it. But if you can afford Accel, MSD or OEM, by all means avoid them.

I bought an 8 pack set for my Lasso Ford F-150 and found 4 ignition coils was bad. I started my engine. ran in rough reverse and finally stopped after a few minutes of running. I got myself a coil spark tester and found that 4 coils were bad by checking each coil. I would not buy these Chinese fakes, they are complete rubbish. I sent them back for a refund. I'm going to buy a set of Ford ignition coils instead to avoid this problem for the next few weeks.

Love these coil packs. I'm a certified mechanic, installed them on my tour motor on my tour along with a standard 20lb rig. I installed their coils and woke up on my engine, you can hear the cams getting sharper and that added about 8 more horsepower to my dyno. I received them all in good condition except 2. I emailed the supplier. A day later they replied and agreed to replace the defective items. I'm a lifetime customer. They stand by their products.
