| Customer Reviews: Average Rating:  Rating : - Lexus IS300 w/ 90K miles Hello, I was skeptical about this product at first. My idle RPM was kinda low and the car would vibrate at times during the idle, especially when the A/C engaged. I used the seafoam and my idle has been smoothened out, throttle response seems crisp, and the car overall feels a lot better than before.
I highly recommend this product. + See Full Customer Review |  |
