Rev Ignitioncompatible with GM 05-14 Square Style 12611424 High Performance Ignition Coil Set of 8 RD1007R

Racing

I replaced factory originals a year ago. Due to a occasional rough/skip idle. They definitely look good and they have worked just fine eliminating the issue I previously had. They are very competitively priced vs vehicle OEM. I just completed a 5000+ mile vacation drive and everything is running fine. A very good product in my honest opinion.

As soon I installed these new ignition coils I took my car for a test drive and immediately I felt the difference between OE coil and these performance ones great buy

son excelentes las puse en un GMC sierra 2014 y cambio total mente el motor,principalmente en el encendido,mi camioneta no encendia bien ,era inestable el motor y quedó como cuando la compré que era 0 millas .Recomiendo que cuando lleguen a 80.000millas cambien las bujias,cables y bobinas por lo menos es mi experiencia en mi camión que tendrán un cambio significativo en cuanto al encendido y la potencia. gracia por resolver mi problema al100%

I bought the coils for my 09 Impala SS, 5.3L LS4. Eight of them came nicely packaged, and bolted right in. My car had a multiple cylinder misfire code and between new plugs, wires, and coils the code is no longer present and car runs perfect. Also gave the engine bay a nice little pop of color as I installed these and red spark plugs wires. Be sure hit hit auto parts stores tho, as the coils don’t come with die electric grease.

Works OK so far installed on a 5.3L Pontiac Grand prix GXP model along with new wires and NGK spark plugs still works good after a month I have no way of knowing if they put out 10 to 15 percent more than stock coils I don't know how much the stock coils put out.

Happy with delivery time and also like that they are easy to install.

These are very nice and strong coils. You will a difference right off. Instructions easy to read.
