After replacing two radiators, I decided to go aftermarket. Stillen has a good reputation. The replacement radiator was on sale (always a bonus). The radiator fit although the fan shroud needed to be trimmed. I knew that going in. I haven't driven it far, nor are we in the hot weather/stalled in traffic zone, but I have every expectation the radiator will perform as advertised. A purchase with no regrets.

Fits perfect holds up amazing great materials

Awesome quality good fitment and instructions.

I was in the market for a cold air intake for my 2011 hyundai elantra to give it a little more h.p due to the high mileage (300k). As we all know in 2025 there's a million websites to order/ buy things however, Stillen had the best price out of everyone! Thanks again for your professionalism, best price, and fast shipping! Definitely will order/ purchase from Stillen again! 5 star 🌟!

Great product and performs as promised.

The install was a little tricky without an accurate picture of where some of the sensors were, and you need little hands to reach the turbo pressure sensor, but I did notice an instant improvement in throttle response and MPG improvement.

I recently purchased this item for my 2022 Powerboost and it was very easy to install and set up. Instructions were straight forward and once I set my tunes to fit my driving style I noticed a 2-3 mpg gain on eco mode and even shaved a half second off my 0-60 time. I have 33’s and a 3” lift on my Powerboost but I am certain I would be in the 4’s with the TruControl no problem. You will definitely notice the torque and hp gains!!

Install was a breeze, took me 5 minutes. Definitely noticed a pick up in throttle response and turbo spool. Would highly recommend for anyone wanting a simple upgrade that actually works.

There was a slight delay in shipping due to the holidays, which was explained to me by customer service and I really appreciateed the communication and honesty… BTW, The fitment was absolutely perfect. Great Job Team!

Gives a cool and different look to the Q60.

I bought it and easy install and I feel the diffrence!

Great addition to my Silverado almost a perfect fit, not enough to even worry about, solid material much thicker than OEM. Looks great too!

This product works and looks good. The holes were a little off but not hard to correct. Overall a good quality well built product.

Do all of the tunes require high octane fuel or do some of them work on 87 octane? I see you have an eco mode, what kind of mileage gains are you getting with that?

Does this fit tahoes yet and if so will it fit the new 2025 Tahoe if not is it in your plans?
