Perfect fit
The manifold fit perfectly, came with all the parts I needed and performs beautifully. No more lawnmower sounds coming from my engine. I appreciate the dry fast shipping time and ease of ordering from the website. I will definitely be ordering parts from here in the future and will recommend 1a auto to anyone looking for parts.
