When you use the best ignition coils for your Acura TSX car, the vehicle’s engine offers you maximum torque and horsepower consistency. But average aftermarket coils can suddenly drop RPM that makes the car hard to drive.
There’s a thin lining between running long and staying helpful for a long time. Unless the coil pack transforms battery voltage higher and transfers spark plugs right on command, the engine keeps pausing.
Mounting new ignition coils after a certain period is necessary to keep up the actual engine conduction even if the car is something as reliable as Honda Acura TSX.
I’ve listed ten ignition coils that can be responsive enough to Acura engines for better driving experiences. Have a look at their reviews to know which one helps your car engine most.
Does All Acura TSX Fit Same Ignition Coil?
Hang on a minute before jumping into a product! Does your Acura Tsx have a 2.4L V4 engine or is it a 3.5L V6? Acura TSX has two types of engines such as K24Z3 and J35Z6 which the company has used in the models 2.4L L4 (2004-2008) and 3.5L V6 (2010-2014) respectively.
The table below shows the summary of the reviewed products that would be fit for these two types of engines:
|Acura TSX (K24Z3) 2.4L L4 (2004-2008)||Acura TSX (J35Z6) 3.5L V6 (2010-2014)|
|Dyoss Ignition Coil||NPAUTO Ignition Coil Pack (set of 6)|

How To Choose Ignition Coils For Acura TSX?
Finding the right replacement coil for your engine, may sometimes take a heavy toll on you. But do you know just checking a few things before buying the coils, can make the search easy. Following is the checklist which should lead you to the right ignition coils:
Type Of Coil
The basic coil designs are single coil, coil packs and coil-on-plug. Pick a coil type that will fit most in your car’s ignition system.
Single coil: To power up all the spark plugs at a time, your engine will need only one coil. You can mount the single coils inside of the distributor cap.
Coil packs: You will need coil packs when your engine has multiple cylinders. Following is a common configuration which shows the number of coils you will need for multiple cylinders:
|4 Cylinders||2 Coils|
|6 Cylinders||3 Coils|
|8 Cylinders||4 Coils|
Coil-on-Plug: Each spark plugs of Direct ignition system need single coils to create durable sparks. The coils can be located near or over the plugs.
It shows the level of power that transfers to the spark plugs through the windings. In order to provide a high amount of power to the plugs, each coil needs to have a minimum primary resistance. However, depending on the engine type, the value of the resistance will differ.
You can use a multimeter like the KAIWEETS digital multimeter to measure the resistance of the coils.
Make sure the resistance is not too low to damage the distributor points. So, you should buy a coil by ensuring that the primary resistance would be compatible with other parts of the ignition system.
To show the comparison of the numbers of the windings used in primary and secondary circuits, we use turns ratio. The higher ratio presents the higher amount of voltage. For example, 2006 Acura TSX has a ratio of 10.5:1.
Maximum Output Of Voltage
Generally, an Acura TSX can produce around 12 to 13 volt power. So, when you purchase an ignition coil, check whether the coil can help the engine to produce that much power.
Replacement Part Numbers
You should match the replacement part numbers with the original parts. It will ensure that you are choosing the right parts as replacement in your ignition system. One thing you need to remember, the numbers will vary according to the car models and their manufacturing year.
For instance, MCK ignition coils will be a perfect fit for Acura TSX 3.5L V6, if it has been manufactured between 2010-2014 but they will not fit on the cars which have been assembled between 2004-2008.
It would be better for your engine if you choose coils made by the original equipment manufacturers. They use the same materials and also follow the same specifications to make the replacement parts.

Frequently ASKed Questions
What are the symptoms of Bad Ignition Coils?
If you see the following signs in your car, the chances are that the ignition coils are failing:
Check Engine Light (CEL) Illuminates: When the coil fails, it causes misfires in the engine and the illumination of CEL indicates this problem. You can use an OBD2 scanner to check the issue. If the scanner shows error codes from P0300 to P0312, it means there is misfire in the engine.
Slow Acceleration: Due to the coil failure, the engine will lose its power to speed up your car. So, when you press the gas pedal, you will notice that the car is hesitating to accelerate and you are not getting the desired speed.
Idle Gets Rough: Another symptom of the bad ignition coil is that the engine will not run smoothly when you are idling. You will also feel a vibration in the cabin.
Excessive Fuel Consumption: One of the most common indications of the bad coils is, the engine starts to consume an excessive amount of fuel. When you see that you are not getting the usual gas mileage, you should understand that you are having ignition coil failure.
Difficulty In Starting: As there would be a lack of ignition energy, your engine will take longer to start or worse it will not start at all.
What Can Cause Ignition Coils To Go Bad In Acura TSX?
There are several reasons which can damage the ignition coils prematurely such as:
Oil Leakage In The Spark Plug Wells: Due to the oil leak in the spark plug tube, your engine can face misfires and eventually can damage the coils. The leakage mainly occurs when the tube seals are poor in quality. So, you can solve the problem just by replacing the seals.
Faulty Connectors Or Wires: When the electric wires connected to the ignition coils get damaged, they cause power failure in the ignition system. To be sure of the faulty connectors, you are suggested to use a code scanner like Foxwell OBD2 scanner for Acura TSX. If you see the error codes between P0350 to P0362, it means your engine has circuit malfunction.
Blown Fuse: If the fuse gets blown, the circuits will be interrupted and the coils won’t be able to produce power to ignite the engine. In order to check the fuse, pull it out with the help of a fuse puller and then hold it against the light. Notice whether the metal strip in the middle is broken or not. If the fuse is faulty, the strip will be broken. In that case, you will need to replace it with a new amperage which can provide the same amp rating.
How To Replace The Bad Ignition Coil in an Acura TSX?
In order to replace the coils you will need the following tools:
- 10mm socket and ratchet.
- 5/8″ spark plug socket with extension.
- Anti-seize lubricant (if necessary).
- Torque wrench.
Now, processed according to the given steps:
- Step 1: Remove the plastic engine cover of the engine by using a 10 mm socket.
- Step 2: The coils are kept in place with 10 mm bolts, so use a ratchet to remove them.
- Step 3: You need to disconnect the spark plugs from the coils. Take a 5/8″ spark plug socket with extension to release the plugs.
- Step 4: If necessary, use a little amount of anti-seize lubricant on the threads of each plug so that they don’t get locked up or stuck in the engine block. You can use Permatex 80078 anti-seize lubricant in this process.
- Step 5: With the help of a socket put the plugs on the right place and torque them to 156 in-lbs and make sure you don’t over tighten them.
- Step 6: Install the new ignition coils and then plug the connectors with them.
- Step 7: Put the bolts and plastic cover back on the engine in the reserve way.
How To Maintain Ignition Coils?
It is important that you maintain your coils on a regular basis because it will make them last for a long period of time. Below are some tips for the maintenance:
- Ensure the coils are not overheated or damped.
- When the engine is not running, don’t turn on the ignition switch.
- Check, clean and tighten the circuits regularly to avoid short circuits.
- To avoid overvoltage issues, control the engine performance.
- Dry the moisture of the coils with clothes, don’t roast them with fire.
To sum up, it is important that you have good quality ignition coils in your engine because they play the main role to power up the engines. To be sure that you are getting the right parts, you are suggested to see the checklist while buying the coils.
Moreover, install the coils properly by following the given steps. Otherwise, even if you get the right parts, they will not work on your car. Lastly, in order to ensure their long durability, don’t forget to maintain them regularly.
