Specifications
Banks Ram-Air filter is a high-flow air-cleaner element that decreases intake restriction and sends more cool, dense ram-air into your engine. Even wet or dirty, Banks Ram-Air filters outperform conventional ones, because the multi-layer design traps moisture, dust and debris on the oiled, outer surface, allowing air to move through with ease.

Reviews

I’ve purchased multiple BANKS performance

"I’ve purchased multiple BANKS performance products and have no complaints AIR INTAKE MONSTER RAM INTAKE MANIFOLD INTERCOOLER & BOOST TUBES REAR DIFF COVER SPARE AIR FILTER Highly recommend all BANKS products. Very happy with quality and all products purchased."

— Brandon O. (5/5)

Great filter

"I bought this filter to have a second filter to change out with while the one that came with the ram air kit, which is an oiled filter, when cleaning it. It seems to work better due to it won’t put oil residue on sensors and triggering CEL, wish it would have been available when I ordered the kit. Only thing is it doesn’t give directions on cleaning."

— Michael W. (5/5)

Recommend a second filter

"The Ram Air system works as advertised. The response of the engine as well as the fuel mileage improved as stated. I had to order a second filter due to the original getting dirty and the expected rainy weather when I got back home. These filters work well and are easy to clean, but I needed my truck, so I purchased a second filter."

— Michael L. (5/5)

Perfect Fit

"Work in the parts department at a dealership, Matched the filter # to the one on the vehicle and came up with this, worked perfectly for us, we managed to make some good money off of it and the customer was happy. BANKS always makes a great product"

— Jarred O. (5/5)

Good quality and can hear intake more profoundly

"Prefer this over the oiled filter because it lasts longer and is easier to maintain. Also the dry filter has the advantage to keep because if you forget to re-oil or do not add enough oil, you can cause cylinder wall damage and scuffing"

— Bryce L. (5/5)

Replaced intake and exhaust

"2012 Jeep Wrangler JKU - I replaced thr intake and exhaust (cat back) with Banks systems and was woefully impressed like always. I run Banks in two trucks and this was a first time in a vehicle not a truck. Right now I am running 24MPG highway and 20MPG city in a Jeep which is unheard of. Only downside is I dont have a means for running a snorkel, saving money none the less."

— Derek (5/5)

Excellent, very happy

"I just used the wet one that came with my kit but decided to get the dry one (with the sock) for my style of driving and the places that I go. I absolutely like the cold air intake. worth every penny, many steps above most other brands."

— Eddie H. (5/5)

A little "pricey," but I

"A little "pricey," but I am sure I can trust the Performance and Quality of this Filter. After watching a Banks Video (comparing a Banks Filter to an S & B Filter), I was shocked on how much the Banks "out-performed" the S & B Filter by a mile! I know Banks fully Engineers and Test their Products. . . . a real "plus" these days."

— Harold H. (4/5)

Works Great

"This was bought to be able to swap with my other one between cleaning and oiling. Its more efficient to have one sitting on the shelf to swap out during servicing. As with all of the Banks products that I have purchased they excellent quality."

— Jason H. (5/5)

BIG Filter

"Perfect fit in the Ram-Air! Big improvement over stock filter!"

— Chris A. (5/5)
