Review on 🚗 ECCPP Portable Spare Car Ignition Coils Compatible with Mazda Protege 2001-2003 - Pack of 2 for Travel, Transportation, and Repair - UF407 5C1208 Replacement by Luis Shreibman

parts failed in less than a month with a series of random misfire codes. When pulled off, the rubber boots did not go through the hole in the cylinder head cover, causing them to fall onto the spark plugs. I had to buy special pliers with narrow needles to fish them out. Checking these two coils clearly showed that they don't even match (see photos of boot ends of different styles). Upon further inspection, cracks were found on the plastic ends (see photo). These cracks, along with the very brittle, loose and light rubber boots, eventually led to the cylinder head buckling. Tip - don't waste your money buying cheap Revain fakes at half price. The cheapest O'reilly's Auto Parts own brand has completely solved the problem and has a lifetime guarantee.
