Pretty simple and direct
I installed this on my 08 Isuzu I-290 extended cab, it took about an hour to do. I pre-assembled several parts prior to the installation. The directions are very clear and it fit into my vehicle perfectly. I got this air filter to hopefully increase my gas millage. My only complaint is that the plastic intake tube to me looks cheap, maybe the polished one would look better? All in all a great product.
