Cold Air Intake
Out of the gate the White Rhino put down 355 hp with 383 lb-ft of torque, numbers I could easily live by. But I have this genetic predisposition, not unlike Tim Taylor, that nudges the back of the more primitive part of my brain with the thought that there’s always more to be had, and not with a lot of wrenching.
I put a K&N cold air intake on my Silverado hoping to get more out of its remarkable 4.3 liter V6 for towing on grades. Its performance improvement was impressive, especially in the low end department; more grunt and fast off-the-line times, but, alas, it was still a V6, a power plant that would’ve been perfect in
the Nomad.
When I first picked up the Rhino I went with a K&N high performance filter which produced a noticeable difference, especially in fuel efficiency, but my internal neanderthal was still unsatisfied.
Since the Rhino spends a lot of time in super dusty and wet conditions, I wanted an intake that was closed to the engine compartment and with such criteria my search landed me at
CARiD where I discovered the aFe Momentum XP aluminum closed cold air intake system.
The airbox is sealed from the engine compartment using the stock inner fender opening and there’s a pre-filter available for the conditions we drive in. You may be wondering, why not a snorkel, and the answer is there’s not one yet available.
Its specs claim a 15 hp boost with up to 21 pounds more torque.
The box has a window in it to easily check out the filter’s condition at a glance, which up front I really liked, but the reason the window is there is because accessing the filter requires removal of the intake tube. No big deal, takes a little more time than unscrewing the fasteners on the stock box, but it’s a bit of a hassle to put on or remove the pre-filter. This would’ve been super if the sealed box had a removable lid with quick-release clamps, especially at its price-point. Ouch.
The tube comes in brushed aluminum or textured black and has a port for the stock MAFS and inlets for breather tubes. Installation is very straight forward and took about a half-hour.
Results? Along with a
cat-back three-inch exhaust and performance muffler, let’s just say my inner Toolman is very happy. I now need my traction control on to keep me civilized, otherwise the squealing Grabbers draw more attention than I’d like. We’ll see what it does for fuel efficiency if I can keep my foot out of it.
Pros: Great fit and finish, easy installation, and more power as promised.
Cons: Expensive at $33 per horsepower gained, and a hassle to change out the pre-filter.
