Ah Hoover, my old stomping grounds. I have some experience, just not the good kind. It looks good in the pictures though, only thing I see wrong is no a/c. Heat index near 110 today and humidity above 60 percent. If it were me, I would also ditch that filter and go with something else. That style filter is junk when it comes to actually filtering the air. Plus its right next to the header, can't be good for taking in cool air. Take that charcoal canister bracket near the fuel lines and clean the engine bay also. Good luck

 

Nice looking Mariner!

I would get rid of that air filter. I am pretty sure that foam HKS filter is pretty bad at trapping all of the dirt....
