Very Satisfied
Reviewer: Raagnorak
11/10/08 07:57 AMThe spark plug boots I ordered are exactly as described at PartsGeek. I shopped around and found the best price at PartsGeek, even including the shipping charges. Not only that, but the parts were in my hands in three days. PartsGeek is easy, inexpensive, and quick. My wife's toyota is a 1999 with high mileage, stuff is breaking down every other week. I will be looking to PartsGeek first to find replacement parts, and I am recommending PartsGeek to my friends and associates who will also need parts for their cars. Thank you PartsGeek.
