The 6.4 HEMI Intake Upgrade Instructions. The 6.4 HEMI engine is well-known for being a strong V8, especially with some simple bolt-on improvements. The first version of this engine, with 525 horsepower and 510 lb-ft of torque, was released by Chrysler in 2005. Dodge released the 6.4 HEMI in their SRT8 lineup in 2011, with 470 horsepower and 470 lb-ft of torque.
A cold air intake improvement is one of the greatest solutions for individuals looking to increase their power and performance. These 6.4-liter engines respond well to changes, but how do they react specifically to an improved air intake? Cold air intake modifications increase power, efficiency, and induction sound. Simply put, increased airflow allows for increased power.
The many sorts of available intake enhancements provide varying benefits. This article will highlight some of our most highly suggested air intakes and discuss their various benefits. For more information on your 392 HEMI, see our earlier post on the four most typical 6.4 Hemi engine problems. We shall use the following nomenclature in this article: 392 HEMI, 6.4 HEMI, Dodge, Jeep, Chrysler, or Ram 6.4 HEMI. To avoid any confusion, these designations all refer to the same engine.
6.4 Advantages of HEMI Intake Upgrade
This tutorial will assist you in analysing the benefits and gains of upgrading the intake on a stock 6.4L HEMI engine. The stock intake of the 6.4 HEMI is efficient on engines that have not been heavily modified. However, when your horsepower increases, an upgraded cold air intake may be required to realise your engine’s full potential.
Stock intake systems in the 392 HEMI can limit supporting changes. It is critical to properly balance your vehicle’s upgrades and changes. To maximise your car’s performance, you’ll need a variety of supporting upgrades, not just one, regardless of its quality, price, or promised promises. The following are some of the advantages of a 6.4 HEMI intake upgrade:
- Gains of 3-10 horsepower
- Gains of 5 to 15 wtq
- Improved total airflow by 20-50%
- Improvement in MPG/gas mileage
- improved throttle responsiveness
- Induction noises that are louder
A decent tune and regular engine maintenance can have a major impact on the outcomes indicated above. With a tune, an improved intake may add significant horsepower to the 6.4 HEMI. Thus, without a tune, adequate supporting mods, and correct maintenance, an intake will provide significantly less overall benefit.
Other Systems vs. 6.4L HEMI Cold Air Intake
Cold air intakes are classified into two types: closed and open. To reduce induction noise, closed intakes are housed or boxed within an enclosure. Because there is no surrounding enclosure, open intakes generate the maximum airflow and consequently produce a louder induction sound.
The “short ram” and the conventional cold air intake are two more types of intakes. Short ram intakes are designed to reduce friction and boost engine airflow. Cold Air Intakes differ in that the filter is re-routed to a cooler section of the engine bay, allowing cooler air to enter the intake.
Due to the high demand and ease of installation on many cars, the industry manufactures a wide range of classic cold air intake systems (closed or open). Because our recommended intake changes are easier to install, they are also easier to maintain and fix. Now, let’s get into our list of the top three intake improvements for the 6.4 Hemi engine.
