This company does an extraordinary an invaluable service teaching car aficionados how to repair or replace defective parts in their cars and saving them, along the way, lots of money. Their division of Parts Sales is very easy to understand and fast to navigate as the process of buying and paying. The packaging is as expected very much professional and the shipping fast. With regard to prices after searching on the Internet it appeared to me as if there was an error because they are fair and therefore super affordable. I, wholeheartedly , recommend buying from them. Keep the good work and greetings to all of you. Carlos J. Sevilla-Moreira.

February 17, 2017
This product seems to be the same as the original equipment. So far all coils are functioning properly. Handling tips on removal of old coils and installation instructions of new coils would have been helpful.

Do i have just engine coils in my 2012 ford focus or do i have spark plugs wires and a distributor cap as well? Do i replace all of these for a tune up?
May 14, 2018
Just spark plugs and the 4 coil packs, wires and caps are a thing of the past.
May 14, 2018
Your have plugs and coils. I had a miss I could not find,so I changed all 4 plugs and coil. It worked well. No need to change every tune up. Good for 75,000 miles on coil and 20,000on plugs.
May 15, 2018
Best method is once a year for plugs every 2 years for wires and coils and boots
December 2, 2018
yes if you want a correct tune up replace them all
