So I contacted Northwest diesel LLC to see about getting a diesel swap done on my Nissan Xterra, they were not able to get me in to do this but they have been helping me try to find a shop that can and will Perform the work for me. They have gone above and beyond what most people would do for someone whom isn’t even paying them. Thank you NW Diesel for your commitment to good customer service.

Great shop. Great customer service. Ethan and Nelson are very knowledgeable. As a fellow shop owner, (Subaru repair - NWSS) they’re everything you expect from a repair facility.

This shop is awsome! The owner, Ethan is very knowledgeable and easy going. I purchased a S&BMB cold air intake for my 06 6.0L Ford f450 and now it runs like a champ. Thanks NORTHWEST DIESEL!
