## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome Part , And Awesome Price also quick delivery
*by G***D on May 13, 2025*

It was a perfect fit in my 2010 Lexus RX350 . And the cost awesome here on Amazon cause the dealership wanted a $125.00 for the same part . And is was a good value for my money . And Easing to install in matter of minutes also it is Durability. Heat level . And another thing it was a very quickly delivered and if I needed another one I will buy it again great price and product

### ⭐⭐⭐⭐⭐ Perfect replacement
*by W***2 on June 20, 2025*

Was a direct fit replacement. Great build quality. This versus OEM I saw no differences and this one was 2/3 of the price. I did test with straight water and a pressure kit no issues. Unfortunately never actually had the opportunity to install it because the car got hit and their insurance ended up just totaling it out. Ended up returning this but will always buy trq parts. As close to OEM as you can get without the price

### ⭐⭐⭐⭐⭐ Fitment
*by T***E on September 17, 2025*

Fit like an oem glove on a 2016 1500 BigHorn
