5.7 Hemi Cold Air Intake FAQ
The 1st generation Hemi delivered 350 horsepower at 5,600 rpm and 375 lb-ft of torque (4,400 rpm). The 2nd generation model delivered 390 horsepower and 407 lb-ft of torque in the Dodge Ram, and the 3rd generation hemi reached 375 horsepower in the 2009 Dodge Challenger with a manual transmission. However, the power generated by each Hemi is different between different models of vehicle.
3rd Generation Hemi Engines
The Hemi uses a cast iron block with a chunky deep skirt design. Four bolts per main bearing hold up the crankshaft, the manifold is cast aluminum alloy, and the intake manifold is plastic. This engine is cheaper and easier to build than the LA-series 360 V8 4.7-liter V8. It also produced more power and torque than the LA series models.
The 5.7L Hemi hit the market during 2003 and was found in all Dodge Ram 1500, 2500, and 3500 pickup trucks to complement the Magnum 5.9 engine. During 2004 only gasoline engines were available in the Ram Heavy Duty series. 2014 5.7 Liter Hemi has MDS with 395HP, and the model was installed in Dodge Ram, and Dodge Durango.
In 2005 the Hemi was placed in Chrysler 300C, Dodge Magnum R/T, Jeep Grand Cherokee.
In 2006 it appeared in the Dodge Charger R/T, and in 2009 it was installed in the Dodge Challenger R/T with a 6-speed version that does not feature MDS.
The 5.7 L (345 cu in) Hemi in the Ram delivers 345 hp (257.3 kW) and 398 lb-ft (540 Nm).
The 5.7 L (345 cu in) Hemi in the 300C and Magnum R/T delivers 340 hp (253.5 kW) and 390 lb-ft (529 Nm).
This is the list of applications for the 5.7L Hemi.
|Chrysler 300, 300C||2005–present|
|Dodge Durango||2004–2009, 2011–present|
|Dodge Magnum R/T||2005–2008|
|Dodge Charger R/T||2005–present|
|Jeep Grand Cherokee||2005–present|
During 2009, Chrysler upgraded the 5.7L engine integrating Variable Camshaft Timing or VCT. This system uses an oil control valve to control the flow of oil to a unique camshaft sprocket that contains a phasing device. The valve either advances or retards camshaft timing based on the mode of operation.
The cylinder heads are revised for increased flow, and the intake manifolds are now engine model specific. The heavy-duty trucks have a six-speed transmission with no Multi-Displacement System (MDS), and the latest models of Hemi come in five different camshaft profiles that will all have VCT.
Cold Air Intake Filters
A very popular aftermarket product, Cold Air intake filters are added to engines to improve the filtration and cold air intake for performance upgrades. Air filters are used to stop pollution from entering the engine, radiator, and fuel lines. Air filters are a very important component in an engines life performance. Therefore, when a filter is not performing, the engine will deteriorate, and performance will falter.
These basic air flow and filter units are usually made aluminum alloy with plastic and are ergonomically designed to be changed within minutes. The modern air filter kits must be cleaned or changed at least once a year, or once every 12,000 miles, whichever comes first.
Filters do age, and also cleaning them or replacing them is a matter of common sense. If you drive in especially polluted areas such as construction sites, you should consider changing the filter after 6,000 miles.
Cold air intake filters are kits that provide over stock performance by increasing the flow of clean cold air to your engine. Just so you understand the impact of a cold air intake filter when compared to a stock, it will improve your acceleration by 11%, and a clean filter improves performance by the same degree. As such, you are looking at an improvement of up to 22% from a clogged stock air filter, when adding an aftermarket cold air filter.
