5.7 Hemi Spark Plug Torque Specs

The 5.7 Hemi Spark Plug Torque Specs is a very important number to know when working on this engine. This number helps ensure that the spark plugs are tightened correctly and will not come loose while the engine is running. It is also important to know the torque specs for other fasteners on the engine so that everything is kept within proper tolerances.

If you own a 5.7 Hemi engine, you know that proper maintenance is key to keeping it running smoothly. That’s why it’s important to know the torque specs for your spark plugs. For anyone who may not know, torque is a measure of how much force is required to turn an object.

When it comes to spark plugs, the amount of torque applied can affect how well they work and how long they last. Generally speaking, most spark plugs should be torqued between 18 and 25 foot-pounds. However, there are some variations depending on the specific type of plug you’re using.

So be sure to consult your owner’s manual or a reliable source before proceeding. Once you have the correct torque figure, use a quality torque wrench to apply it evenly. This will help prevent damage to the threads and ensure a tight, secure fit.

With just a little bit of care, following the proper torque specs for your 5.7 Hemi’s spark plugs will keep them working properly for years to come!

• A ratchet • A torque wrench (optional but recommended) • Spark plugs (NGK PZFR6F-11 are the recommended type for 5.7-liter engines)

Assembling Your Tools First things first – gather all the tools you’ll need so you’re not running around trying to find something in the middle of the job. Once you have everything, double check to make sure each tool is in good working condition.

You don’t want to start changing your plugs only to discover that your socket wrench is stripped or that your torque wrench isn’t calibrated properly. If everything looks good, let’s move on to the next step. Finding Your Spark Plugs

The next thing you need to do is locate your spark plugs. On a 5.7-liter engine, there are eight spark plugs, and they’re located under the ignition coils on top of the cylinder heads (see image below). Once you’ve found them, use your finger to check each one for debris or deposits that could indicate a problem.

If everything looks clean, go ahead and proceed to the next step. Removing Your Old Spark Plugs Now it’s time to remove your old spark plugs so you can replace them with new ones. To do this, first attach your spark plug socket to your extension and ratchet and then carefully thread it onto each spark plug – turning counterclockwise until it’s snug against the seat . Next , using moderate pressure , turn the ratchet clockwise until the plug loosens and comes out of the hole . Be careful not to drop any dirt or debris into hole as this could damage your engine . Repeat this process for all eight plugs . Installing Your New Spark Plugs Now it’s time to install your new NGK PZFR6F-11spark plugs .

6.4 Hemi Spark Plug Torque

If you’re looking for optimum performance from your 6.4 Hemi, it’s important to follow the proper torque specifications when installing your spark plugs. The general rule of thumb is to tighten the spark plug until it is snug, and then turn it an additional 1/16 to 1/8 of a turn. However, with the 6.4 Hemi specifically, it’s recommended that you use a torque wrench and tighten the spark plugs to 18-21 ft/lbs.

Not only is following the proper torque specification important for preventing damage to your engine, but it can also affect the performance of your vehicle. If the spark plugs are too loose, they can fall out and cause misfires. On the other hand, if they’re too tight, they can break and cause all sorts of engine problems.

So be sure to use a torque wrench and follow the manufacturer’s recommendations!

What Should Spark Plugs Be Torqued At?

If you’re doing a tune-up on your car, one of the things you’ll need to do is replace the spark plugs. When installing new spark plugs, it’s important to torque them correctly. If they’re too loose, they can fall out and cause engine damage.

If they’re too tight, they can break and also cause engine damage. So what’s the right torque for spark plugs? For most cars, the recommended torque for spark plugs is between 20 and 30 pounds per square inch (PSI).

However, it’s always best to consult your car’s owner manual or service manual to be sure. The specific torque requirement for your car will be listed there. Once you know the correct PSI for your car, use a torque wrench to tighten the spark plug until it reaches that setting.

Then give it an extra quarter turn to make sure it’s snug. Don’t over-tighten the plug or you could strip the threads and cause damage. Now you know how much force to use when tightening spark plugs in your car!

Just be sure to check your service manual first so you don’t accidentally damage anything in your engine.

What is the Torque on a 5.7 Hemi?

The torque on a 5.7 Hemi is 624 lb-ft at 4,400 rpm. The engine produces 375 horsepower at 5,150 rpm.

How Many Pounds of Torque Does It Take to Tighten Spark Plugs?

When it comes to tightening spark plugs, how much torque is required really depends on the specific spark plug you are using. In general, most standard spark plugs will require somewhere between 18 and 25 foot-pounds of torque to be properly tightened. However, there are some specialty spark plugs that may require more or less torque for proper installation.

Always consult your vehicle’s owner manual or the manufacturer of the spark plug you are using for specific torque requirements.

Do You Need a Torque Wrench to Put in Spark Plugs?

No, you do not need a torque wrench to put in spark plugs. Torque wrenches are designed to apply a specific amount of torque to a fastener, and are therefore not necessary for putting in spark plugs. However, it is important to make sure that the spark plugs are tightened properly so that they don’t come loose and cause engine damage.

The best way to do this is to hand-tighten the plugs until they are snug, and then use a socket or ratchet to give them an extra quarter turn.


The 5.7 Hemi is a popular engine for many Dodge and Chrysler vehicles. When changing the spark plugs, it is important to use the correct torque specs. Improperly torqued spark plugs can cause engine damage or misfire.
