Description:

Replaces constricted factory setup; flows up to 66% better than stock. Includes large custom filter housing cover, tubing, adapter and high-flow lifetime filter.
2001-10 models

Banks intake improvements take advantage of the natural supercharging effect ram-air provides. (If you've ever stuck your hand out the window at 60-mph and felt the force working against it, you know what ram-air is.) Banks behind-the-grille Super-Scoop® is 156% larger than the stock piece to harness more ram-air, separate out debris and rainwater and send the ram-air through a 4-inch duct to the high-flow, lifetime Banks Ram-Air filter. That packs cool, dense ram-air into your engine, increasing power and efficiency.

Banks Ram-Air Intake System delivers cool, dense air to cylinders.

• Complete air intake system including Banks mammoth Super-Scoop air inlet and ducting

• Lifetime filter flows more cool, dense ram-air into engine

• Includes service kit for use every 30,000-50,000 miles

• 5-year Limited Warranty (filter: Lifetime Limited Warranty)

Applications:

2001-2010 W-Series Workhorse Class-A Motorhome - With GM 8.1L 496 Engine

Will this air intake kit fit a 2003 C4500 with a 8.1 engine ( Bill Shafer, 11/17/2022 )

No, it will only fit a Workhorse W-Series class A motor home. ( Support )

Hello, I just wanted to confirm this Kit will fit my

2003 Winnebago Adventurer 33'
Workhorse
8.1
Allison

Product code: 49194

Thank you.

Jim ( Jim, 09/29/2021 )

Yes, this kit will fit your Workhorse. ( Support )

I have a 03 Kodiak 4500 with an 8.1 L , I am wondering if you have a cold air intake that will work with this truck , and will the ECM tune will work with this truck ?

thank you ( Jered Acheson , 09/05/2019 )

We do not offer or know of an aftermarket cold air intake for this application but our ECM tuning will absolutely work. We have tuned a lot of Kodiaks w/ the 8.1L so our gains are on par with what we gain on other applications. ( Support )

Does this ram air system require any re-tuning?

Is improved exhaust required?

No you do not need to re-tune but to take full advantage of the extra air flow the UltraPower Custom Tuning would be beneficial. The exhaust is also not required but will help some too. ( Support )

Quick question guys, just ordered your 8.L magnum wires and AC Delco plugs, love em by the way! Will this RAM air intake system work with my 2006 Chevy Silverado 2500HD 8.1L? Or is just for the motor homes?
Thanks. ( Sam, 04/26/2017 )

Sam,

This Banks Ram Air intake is only for the Workhorse RV chassis with the 8.1L. It looks like K&N makes a kit, part# 57-3030-1.

( Support )

I understand this has been successfully installed on a 2001 P32 Workhorse 8.1L. The tube attaching to the throttle body must be heated and changed to fit. This voids the warranty. Is that all? Not a big deal. Remove the tuba and install this kit with modifications then? Is the filter element a K&N or something similar? Any other potential complications, such as MAFS or EGR or other engine ECM input? I still have been unable to find any DIY 8.1L cooling duct setup on IRV2. Thanks

( Scott Barielle, 04/28/2015 )

Scott,

This kit does not eliminate the Tuba up front unfortunately. You reuse that but enlarge the mouth piece going into the air box. It also changes the lid to where the throttle body tube and mass air flow sensor go directly into the side of the air box so that it is more of a straight shot. I'm not aware of any commerically made air intakes anymore that eliminate the tuba.
