Add up to 39 Estimated HP to Your Third Generation Hemi Engine

Although the first generation of Hemi engines was introduced by Chrysler in 1951 models, it’s the 426 CID second generation Hemi, developed for NASCAR racing in the 1960s or the modern gen three Hemi engines introduced for the 2003 model year that come to mind for most enthusiasts when they hear the word Hemi.

By far the most prevalent version of the Hemi engine is the third generation, that’s been available in four different displacements: 5.7 L, 6.1 L, 6.2 L, and 6.4 L. Fortunately, for owners of Chrysler and Dodge cars and trucks powered by the third generation Hemi, K&N offers a wide range of air intake kits that increase engine power and response.

The first of the generation three Hemi appeared in the Dodge Ram 1500, 2500, and 3500 in the 2003 model year. While not exactly a hemispherical combustion chamber as in past Hemi designs, this new combustion chamber is based on Hemi principles, updated with knowledge gained about airflow over the last 35 years along with advice from Tom Hoover, the designer of the second generation 426 Hemi.

The engine displaces 5.7L or 348 CID, and at its introduction produced one horsepower per cubic inch. Upgrades to the 5.7L motor raised output to 390 horsepower.

Chrysler upgraded the 5.7L to create a high-performance 6.1L version of the third generation Hemi. A revised block with an increased bore, forged crankshaft, lighter pistons, and heavy-duty connecting rods were all part of the modifications. All were installed in the SRT-8 series of vehicles.

Based on the original third generation 5.7L Hemi, Chrysler enlarged to produce additional horsepower, at current the engine develops 485 horsepower in its most aggressive form. While it shares the same displacement, it shares nothing in common with the 392 crate motor Chrysler offered about 10 years ago. What it does share is the displacement with the final first generation Hemi, which was the engine to beat in Top Fuel drag racing until the second generation 426 Hemi was introduced.

For 2015, Chrysler engineers created a new engine, based on the bore of the 6.4L Hemi and the stroke of the 5.7L, creating an engine with a displacement of 6.2L. While all the usual high-performance upgrades have been included, the largest contributor to the massive increase in power is the 2.4L twin-screw supercharger that produces 11.6 pounds of boost. Rated at 707 horsepower, it’s the most powerful street engine Chrysler has ever built and the highest output of any muscle car, regardless of decade.

K&N air intake systems are designed to increase airflow into your Hemi engine over the factory intake system. Plainly stated, K&N guarantees that by removing your restrictive factory air intake and replacing it with a K&N system, your engine will produce more power. To back up that claim, before they’re offered for sale every K&N air intake system is dyno tested to verify the estimated horsepower each kit will produce.

K&N air intakes systems are easy to install on your Chrysler or Dodge car or RAM truck. A typical air intake installation can be completed with a simple set of hand tools in less than 90 minutes. K&N intake kits utilize existing factory holes and mounting points, both for ease of installation as well as not requiring any holes to be drilled in the vehicle.

K&N developed the first air filter that could be guaranteed for one million miles of use. That same confidence in our product extends to our high-flow air intake systems. K&N air intake systems are precisely engineered and constructed with the finest materials, and the company stands behind them 100% with the K&N 10-Year/Million Mile Limited Warranty.

Some intakes are not legal for use on pollution-controlled vehicles in California. View the individual product pages for each intake to view CARB status.

*Horsepower gains vary among products and applications, but each K&N performance air intake system is designed to increase airflow efficiency for specific vehicles and their engines. Each kit undergoes significant testing to help ensure that the filter and intake tube are engineered to deliver large increases in airflow and horsepower.
