Upon receiving the part i was a bit skeptical. The box had been opened and rewrapped in the waxed paper. I conducted a flow test in the truck and was good. The only reason i did not give it 5 stars was part had been opened from its sealed plastic bag. Other than that price was the lowest service was outstanding great job to the Geno team.
Owner Response:Ken, Every so often we will pull a part to take photos/measurements of the product. We will never sell a used or tampered with sensor as new. -John
