Good look and are working well
These are a must! High mileage vehicle that needed an update cause stock coils were going bad. This kit was the same price for 1 oem ignition coil from dealer. Definitely woke the vehicle up and feels like the it has more power and the throttle repose is alot better. 5star!!
I loved 100% recomended
I returned these items. Has my credit been issued????
