I need a driver side manifold without the air pump. Can you help me?Keith P.Feb 09, 2022
Best Answer:Hi Keith, I'm pleased to assist you. Upon checking, we currently do not have the driver-side manifold for this group of vehicles. You may want to consider purchasing a heavy-duty hand cleaner and degreaser, good to have around your home and garage. Click on the link below to see and order while supplies last. You'll get a 30-day post-purchase price match guarantee with your order. I hope this is helpful.

I need to find a exhaust manifold with air injector for a 2001 GMC SIERRA 2500HD 4×4 8.1 LITER ?LizzyMar 31, 2021
Best Answer:Hi Elizabeth, I'm pleased to help you out. This part is guaranteed to fit the 2001 GMC Sierra 2500 HDSL, SLE, SLT 8 Cyl 8.1L. The air injection system is not part of the manifold itself, it is a separate part designed to introduce clean air to the engine exhaust as it exits the exhaust manifold or exhaust headers. Upon checking, we currently do not have in stock the direct-fit air injection for the vehicle. To get back to the product page, please click the link below. Glad to be of help.
