Review on 🔥 Enhanced Pack of 8 Straight Boot - Boost Ignition Coils Efficiency by 15% - Compatible with Ford F150, Lincoln, Mercury V8 V10 4.6l 5.4l 6.8l - DG511 C1541 FD508 Compatible by Anthoni Hayes

Very satisfied! My '06 Mustang GT had a rebuilt engine installed last year after I repeatedly overtightened the original timing chains for inexplicable reasons. My new engine is great and I put new spark plugs in when I installed it, but it still had some of the old engine in it like the original coil packs. I added a cold air intake and quickly tweaked the ECU, which should have improved not only performance but my mileage, but fuel economy has dropped significantly with the new engine. I bought high performance coil packs thinking it was one of the cheap and easy ways to improve things and wanted to order some that cost about 4 times as much from a high performance parts supplier. Then I noticed them and thought about the price, why not just try it? I'm glad I did. My car has brightened up, mileage has increased, and the red paint adds color to the hood! At least they are a step ahead of the worn out OEM coil packs. I can't compare them to more expensive packages due to my lack of experience with others, but I can say that they have made a noticeable and pleasant difference.
