Corolla coils for sale 2014. Quantity: 3 pieces. Original Denso agency. One of them malfunctioned and I replaced them all. Without checking which one was faulty. Now the set of 4 is available. But for sure, one is faulty and 3 are working. Whoever buys them, they should take them all, and it will be clear which one is faulty. Or if you want to test them before buying them on your car, I have no problem. For sale to the highest bidder. I bought the four for 1040 Riyals. Each piece for 260.
