Very fast shipping

I was able to use the online chat to confirm that this Banks 25976-1 intercooler would fit my 2002 Chevy 2500HD LB7 Duramax very quickly. It was at an excellent price and free shipping.

Just received the unit, I will update a review after installing the unit and a 90-day test/use period. Thank you

I ordered 2 day shipping and got it after the 2 days. I requested my shipping charge be refunded and I got a reply saying it will be. I'm happy now!

Good prices and product availability.

Exactly what I needed in a time frame that works perfectly. Checking out was simple. So far, miles from dealing with Vivid.
