However, how often should you change spark plugs in a 5.7 Hemi?
With the HEMI V8 engine, spark plug replacement requirements are based on model year and displacement. The first HEMI engine, the 5.7L, required replacement every 30,000 miles. This interval for this engine continued until 2014. In that model year, the replacement interval was extended to 100,000 miles.
Equal, what brand spark plugs does Dodge use? SPARK PLUG BRANDS Today, you may find some GM or Ford engines factory-equipped with Bosch spark plugs, Mazda engines equipped with Motorcraft spark plugs, Chrysler engines equipped with NGK or DENSO spark plugs, and so on. Most late model Saturn engines use NGK spark plugs.
As a result, what's the best spark plug for performance?
The NGK 6619 Iridium IX Spark Plugs snags the top pick in our spark plug comparison because they offer the best mix of high-performance, fuel efficiency, durability, and dependability. Featuring an iridium construction, these high-quality spark plugs provide a longer lifespan than copper and platinum spark plugs.
Is the 5.7 Hemi really a Hemi?
Says Lee: "Everything else, in terms of the valvetrain arrangement, the shape of the chamber, is in fact a true Hemi. It's not as huge as the old Hemi, of course." At 345 hp, the 5.7-liter Hemi V-8 has 100 more hp than the 5.9-liter Magnum V-8.

Low quality fuel can
cause the hemi tick
. Fuels that contain high amounts of ethanol or that are low octane may not properly lubricate the fuel injectors
and can lead to a slight tapping or ticking noise. Low-octane gas has also been known to cause an ignition knock in high-performance engines
5.7 Hemi engines are good for 250-300 000 miles and more if properly cared for and regular maintenance is carried out. Early models suffered from valve seat issues which was rectified after 2008. It's not uncommon to find high mileage 5.7 Hemi trucks running around today.
The 5.7 hemi is practically bullet proof/reliable. Introduced in 2002 for the 2003 model year, not much has changed in the design other than the VVT & MDS & intake manifold.
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Another common reason for seeing a check engine light is faulty spark plugs or plug wires. Your spark plugs and wires are what ignites the fuel/air combo to make your engine turn. Old or faulty plugs and wires can cause weakened engine performance and poor fuel economy at best.
So even if you're trying to save money on spark plugs and don't care about longevity, OEM plugs are still the way to go. They'll ensure maximum performance and fuel economy, and that will save you on one of your largest vehicle expenses (fuel).
In short, yes, in some situations spark plugs can increase horsepower. ... These 'massive' gains of one or two per cent generally won't be exceeded, even if you're replacing really old and worn spark plugs for new ones. In this case, your essentially just restoring your car back to its peak performance.
In conclusion, both Denso and NGK iridium spark plugs are stable and unrivaled when it comes to longevity. Iridium is less conductive than copper spark plugs but it works well at low temperatures and lasts way longer. ... If you are more concerned about the horsepower of your vehicle, then Denso is a good pick.
Installing high-performance spark plugs can smooth out a rough idle and get your motor purring immediately. Pulstar spark plugs can give your engine more power, a quicker throttle response, and a more stable, longer-lived engine.
Arrington says (the 5.7) the internals will not handle more than 650hp for the rods/something around there. Crankshaft handles up to 650 hp.
The performance gains that are possible with this intake can be as much as 14 horsepower or 19 pound-feet of torque at high RPMs.
The Hemi engine, by design, does a better job of burning all the fuel in the cylinder. Also, because of its design versus a flat head, the surface area is smaller and that means less heat escapes, plus peak pressure can be higher. Also advantageous, is the size of the valves.
