Product Q&A

Can this part cause me to lose power and is it best to change all 6?ALISHA P.Apr 11, 2021
Best Answer:Hi Alisha, I'm glad to assist you. Yes, it is best to order a complete set so every ignition coil is brand new and would not give you intermittent problems if the older ones get defective and it would be costly on the labor. The set of 6 is with part number SET-REPG504601-6. Please click the link below to order the set kit and take advantage of the sale kit promo lower priced. I hope this helps. Happy shopping. <a href="https://www.carparts.com/ignition-coil/drivewire/set-repg504601-6?&vehicle[cylinders]=6&vehicle[liter]=4%2E2&vehicle[submodel]=LS&vehicle[model]=Trailblazer&vehicle[make]=Chevrolet&vehicle[year]=2003?&can=CPJE1043" target="_blank">https://www.carparts.com/ignition-coil/drivewire/set-repg504601-6?&vehicle[cylinders]=6&vehicle[liter]=4%2E2&vehicle[submodel]=LS&vehicle[model]=Trailblazer&vehicle[make]=Chevrolet&vehicle[year]=2003?&can=CPJE1043</a>
