Is there a way to take out the filter?

There is no in cab filter that I am aware of. I think at one point there was a kit offered but I do not have it in my truck.

Been insanely hot the last week and I can say I see a big difference from pre coil clean and Max Assist install.

Really not hard to do and with a hose wand I didnt get any in the cab. Just pay attention to where you are spraying.

It is worth the 48 bucks in my opinion. Or there is always the ball valve route that is cheaper but you have to manually turn it on and off.

Napa sells a foam that sticks and hangs on the core pretty good..

If it hangs there what is the point? If you have to dig that far you might as well wash it anyway. Or am I missing something, just curious.

Nice write up :thumbup:
I just put a ball valve on mine.

Thanks for the write up. I just finished doing this on my truck. Blows much better!

Some trucks are already setup with a unit that does the same thing as the max assist I believe. Correct me if I'm wrong. I have a piece already in my heater hose line from the factory.

By the way, good write up. I took my blower out one time but do not recall the coil/heater core being clogged. Will have to double check.

My air does not feel like it blows as much as the sound it makes on high. I could have sworn my 99 used to blow harder but it could just be me
