Service Details
European Aftermarket Parts & Installation
You didn't buy a European car to leave it stock. NW Autohaus is where the build happens. We source parts from over 30 aftermarket brands and install everything in-house, on the same lifts where we do factory service.
Our techs work on BMWs, Audis, Porsches, Mercedes, and VWs every day. That knowledge is what makes aftermarket work safe and reliable. We know the clearances, the wiring, and the software. When we bolt on a header or swap a turbo, it fits right and runs right.
What We Work With
Intakes, exhaust systems, downpipes, headers, intercoolers, turbo upgrades, ECU tunes, wheels, tires, suspension, clutch kits, fuel system components, and full engine builds. If the part exists for a European car, we can probably source it and install it. The full brand list is below.
Need something custom fabricated or a part from a brand we haven't listed? Call us. If it bolts to a European car, we'll figure it out.
How It Works
Tell us what you want your car to do and we'll recommend the parts and the build order that makes sense for your platform and budget. No upselling parts you don't need, no guessing on fitment.
We order the parts (all aftermarket parts require a deposit before ordering), schedule the install, and get it done. If you want to verify the results, our Mainline ProHub 2000-L dyno is right here in the shop. Same building, same team, same day if the schedule allows.

“Audi owner here that always used the dealership for service. NW Autohaus gave my Audi amazing service and went over everything like the dealership would. Jason put the diagnostic machine on my Audi to find out what the idiot light on the dash was about. Very pleased with the service and the price.”

“I called BMW and they quoted me $2500 and told me all this stuff was wrong with the car. Brought it to Autohaus and these guys fixed it for a fraction of the cost in a fraction of the time. Honest, hardworking, and they genuinely care about their customers.”

“Chris is a really unique mechanic. Rarely do you find a guy who both truly loves cars and is detailed enough to tackle complicated repairs. He took on a project of doing the timing chain service for the infamous Audi 4.2L V8. I wouldn't trust anyone else with it.”

“We have older models of Porsche Cayenne and Mercedes 500E and had them serviced at Northwest. We drove from Brookings to Medford to have our vehicles serviced so we can have them working for as long as possible.”
