Spectre offers multiple open element air cleaner housings that look and breathe great. Spectre has many options to suit your needs including our polished aluminum round and oval designs, traditional triple chrome plated round design, cowl induction specific or our 14 inch high flow versions with our Extraflow top. The polished aluminum series are available in both a 12 inch long and 15 inch long oval with 2 inch tall filter or 14 inch by 3, 4 or 5 inch tall round. Our chrome air cleaner assemblies start as small as a 4 inch by 2 inch tall and go all the way up to a 14 inch diameter by 15 inch tall. The cowl hood assemblies are designed to work with the air flow coming in from your cowl hood to maximize air flow and utilize the cooler outside air. In addition, to the different style assemblies, we also offer hardware to put that finishing touch under your hood. All air cleaners are designed to fit carburetors and throttle body injection assemblies with a 5-1/8 inch neck. 14" x 3" Round Filter

In its final GM version, the 6.5L made 215 hp and 440 lb-ft of torque with a rear-mounted turbocharger. Over the next year, we're going to see if those numbers can be pushed up into Duramax territory without giving up simplicity or reliability.While no one would ever confuse the Duramax for the 6.5L, you can certainly see the family resemblance between the two. The cylinder bore (4.06-inch) is the same, the oil filler tube is in the same location, the A/C compressor and power-steering pump are still on the driver side of the engine, and even the engine's main electrical connectors are carried over from the 6.5L.

If you are obsessed with cars or Jeeps, chances are that you are obsessed with horsepower and torque. All of us have a cousin or uncle whose college roommate had a diesel truck that made 5,000hp at the rear wheels. Or maybe you (or we) “used to have” a muscle car that had more power than a Bugatti Veyron. Sure, sounds like some of the fishing stories we’ve all heard. These cars, trucks, and Jeeps get way stronger and faster with time, much like that fish grows. Well, one way or another, our obsessions that are Jeeps also make horsepower and torque. How much, you ask? Well, it literally depends on the weather, but why don’t we look into this a little further and see what some fairly typical Jeeps get for horsepower and torque numbers. How ya gonna pull that one off, Jp? A smart phone app and a back road? Well, we have friends…no, not many, but still one or two. One such friend, or rather business, that tolerates our presence is Airaid, the company that builds and sells air filters and air intake systems out of Phoenix, Arizona.

Airaid has a Mustang chassis dynamometer that we are allowed to use occasionally between 1,000hp fuel-injected and blown Oldsmobile street cars and next year’s production cars. That works for us, and it allows us to give you a real-life idea of what a few fairly typical Jeeps (some of which you may recognize) make when it comes to power and torque numbers. Are we gonna start running every Jeep we have in the book on the dyno? Are we gonna start testing every part we bolt on our Jeeps on the dyno? Are we overly concerned with what our 2.5L four-banger puts to the ground? Not really, but we do hope this will give you an idea of what numbers these Jeeps make at the rear wheels, what you can expect from a similar build, and some plain old fun reading entertainment. And if you like this article, let us know and we’ll set up a few more dyno runs with some different rigs. Special thanks to Airaid, Trent McGee, and Donovan Shafer for helping this story happen. Our buddy, Mike, is a life-long Jeep nut.

With several Jeeps to pick from we twisted Mike’s arm and got the keys to his recently restomoded ’76 CJ-7. The Jeep has a fresh AMC 360ci V-8 with 9:1 compression built for torque and a little bit of extra power. Fortunately for us, the Jeep put down some good numbers just before something in the T-case went pop as the rollers slowed down locking the rear wheels (so we don’t have enough good data for a dyno graph). As of this writing, we don’t know what happened, probably a bearing seized, but all involved agree (including Mike, who is, remarkably, still speaking to us) that it was good that it happened on the Dyno and not the highway.

Max Horsepower: 211hp @ 4,300 rpm Max Torque: 284 lb-ft @ 3,400 rpm This Willys has been in several tech articles in Jp since the ’00s in one form or another. It’s Feature Editor Simons’ one true keeper car that he has owned since ’99, while others have only lasted a year, two, maybe three. A ’49 Willys CJ-3A now powered by a GM rebuilt even-fire Buick V-6. Simons bought the engine from a junkyard in ’02 from a wrecked Oldsmobile that had a GM Goodwrench engine installed just before the Grandmamobile had a tree jump in front of it. It has a GM rebuild plaque on the block telling about the overbored cylinders and machined crank. The Jeep was run in Third gear with the Saturn Overdrive engaged, effectively turning the 5.38 axle gears to about 4.10s. Vehicle: ’49 Willys CJ-3A

He’s at least a large part of why this story happened. We talked him and the dyno operator and engineer extraordinaire Donovan Shafer into running Trent’s ’97 TJ-based buggy on the dyno. “Trent’s Super Hoopty,” “The Buggy,” “Ol’ Blue,” no matter what you call it, the Jeep can go just about anywhere, including down heavy rock trails or the highway.

The Jeep has seen 20,000 tough miles since being completed. This includes three Petersen’s Ultimate Adventures and a Vegas-to-Billings-in-January frozen road trip. Trent’s buggy has lots of cool parts, including an Atlas four-speed and some bulletproof, yet heavy, heavy wheels. What does that do to the torque and power numbers—apparently, not much? Trent’s buggy put down some pretty solid numbers for a 4.0L. Vehicle: ’97 TJ Wrangler-based buggy Engine Displacement: 4.0L, 87-octane Induction: Airaid UBI system with 3.5-inch tubing and 7-inch SynthaFlow filter Exhaust: JBA header, 2.5-inch tube with Magnaflow catalytic converter and 40-Series Flowmaster Tire/Wheel Size: 37x12.50R17 Nitto Trail Grapplers on 17x9 Spyderlock wheels Max Horsepower: 172hp @ 4,600 rpm Max Torque: 225 lb-ft @ 2,100 rpm You probably recognize our shortened and beaten TJ, sometimes known as the Shrink Ray TJ. If not, know that it has been a pretty budget build with a few tricky spendy parts.

Simons beats on the poor little four-banger TJ with abandon and generally drives it to and from the trail—or from Phoenix to Moab and back. The engine has about 120,000 miles on the ticker just like Trent’s buggy and the Airaid stock TJ, only Shrinky has a 2.5L and an AX5, making it the low-power beater of the bunch. This thing gets less love than a prostitute with leprosy, but thanks to the steep approach and departure angles and flat belly, it can go places where only much larger rigs venture. Vehicle: ’97 TJ SE Engine Displacement: 2.5L, 87-octane Induction: Airaid UBI intake with 3-inch tubing and SynthaFlow Filter, 4.0L throttle body Exhaust: Stock manifold, possible 2.25 after-cat exhaust, Dynomax muffler, dump in front of the rear axle Tire/Wheel Size: 35x12.50R15 Pro Comp MT2 on 15x8 Weld wheels with OMF beadlocks Max Horsepower: 116hp @ 5,000 rpm Max Torque: 139 lb-ft @ 1,700 rpm Occasionally, Airaid plays with an employee’s daily driver and then foolishly allowed us to run it on the dyno for this article.

One such Jeep is this ’98 TJ that is fairly stock compared to the rest of the pack we are testing in this article. With 31s, a hard top, and some aftermarket tricks, this TJ is what our Jeeps used to be and probably what many of your Jeeps were, too. Still with an odometer reading right around that of Trent’s buggy but running an auto tranny, comparisons can be made between this TJ, Trent’s, and even our very own 4-cylinder-powered shrunken TJ.

From a filter to a fully engineered cold air kit, Airaid has intake and air cleaning for pretty much any Jeep in a headlock.
