Q:Fit a 2016 Ford Focus se?
Ayden T.
A:BEST ANSWERHi Ayden, I'm pleased to assist you. This is a universal kit not a direct fit for the 2016 Ford Focus SE. We do not have the compatible exhaust manifold compatible with the vehicle. You may want to consider purchasing heavy-duty cleaning industrial-strength wipes, 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 helps.

Q:Will this fit an 08 impala 3.9l V6 doesn’t specify for v6 or v8?
James B.
A:BEST ANSWERHi James, I'm glad to assist you. No. These are not compatible. We currently don't carry direct-fit exhaust manifolds for the 2008 Impala 3.9L models. We suggest checking the local part stores around your area or the nearest GM dealership directly on what they have available to offer you. I hope this helps, and we thank you for inquiring. Show less
