Kit was a solid 4 star. Could have been a 5 if there was a pedestal base engineered into the kit.

Very easy to install, I noticed better throttle response and turbo sound on a bone stock 7.3L also super fast shipping! Thank you Riffraff Diesel...

Had to either cut out or remove original air box to fit but the truck runs great and you can hear the turbo much better.

I am satisfied with the kit I received from Riffraff. It was shipped and had it a week within me ordering it. I looked around and priced the filter, elbow and fitting itself. This kit is priced great and Riffraff makes it easy. I would recommend it to anyone looking.

The intake fit great, and arrived early! Defiantly made the truck wake up a little bit. I will definitely be ordering more parts from riffraff in the future.

So this is the 3rd of 3 parts that I have installed.

The first was the oil cross over, the 2nd was the fuel crossover - both made the 99 F350 either idle or run slightly quieter.

So I was holding out for the AFE filter for an early 99 and also got the blue cover. Wow this thing is huge. I did a rough calculation and this AFE filter is about 4.5 times larger. By the numbers, the original filter is about 75 square inches. The AFE measures about 346 square inches.

So I have run a few tanks through it. The turbo spins up faster and the EGT's are lower on hills. On some hills, I used to lock out OD to drop it into 3rd to drop the EGT's - don't need to with this air filter.

The turbo is more noticeable, so that offset any of the noise drops with the fuel and oil crossover, and I have not seen any mileage improvements.

Fit and finish are very nice – between the oil cross over, fuel cross over and the powder coated tube, Riffraff does nice work

Overall - very pleased with this last mod as well as the others, and it's pretty too.

Easy to install. You only need a few tools. U can modify the air box if u want to but it’s not needed.
