Don't Remove Bolts
This automotive maintenance tutorial was specifically written to assist owners of the second generation 2014, 2015, 2016, 2017, 2018, 2019, 2020 and 2021 Nissan Qashqai and the 2017, 2018, 2019, 2020 and 2021 Nissan Rogue Sport (USA) in checking or changing the spark plugs in the MR20DD 2.0 liter inline four cylinder engine.

Owners of other Nissan, Infiniti or related Renault vehicles such as the Rogue, X-Trail, Note, Versa, Altima, Maxima, Sentra, Juke, Kicks, Murano, Pathfinder, Armada, Frontier, Titan, Quest, NV200, Q50, Q60, QX50, QX60, QX80 and Renault Kadjar may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) spark plug part number in this 2020 Nissan Rogue Sport with the MR20DD 2.0L I4 engine was the laser iridium NGK DILKAR7D11H (90565).

Another compatible replacement spark plug is the Champion 9412 (REA9WYPB4 laser iridium).

The tools and other items needed to complete this procedure include pliers, a 10mm socket with a 1/4" drive ratchet or a 10mm wrench, a 14mm spark plug socket (or a 9/16" spark plug socket), a set of extension bars, a 3/8" drive ratchet and a tube of dielectric grease.

Please proceed with caution and at your own risk!

Note - You do NOT have to remove the four bolts in order to take off the black plastic "intake duct" (part number 16576-6MA1B) that covers the top of the MR20DD engine.

I didn't realize that the intake duct was only held in place by three plastic pegs that are inserted into rubber grommets on the top of the engine.

I mistakenly thought that the four black bolts had to be removed and only later discovered that I could have just simply pulled it off the top of the engine.

Do Not Remove Bolt
The first two steps are to open the hood and locate the black plastic "intake duct" with the word "NISSAN" on the top that needs to be removed in order to access the four ignition coils.

As I previously wrote, you do not have to remove the four black metal bolts. So ignore those pictures on this page.

The intake duct is just held in place by three plastic pegs on the bottom of the intake duct inserted into three rubber grommets on the top of the engine.

Rubber Air Intake Hose

Squeeze Hose Clamp
Locate the large rubber hose that connects the engine air filter housing to the throttle body on the right (driver) side of the engine.

There is a smaller plastic tube that connects the intake duct to the larger hose.

Use pliers to squeeze together the two tabs on the hose clamp and pull the intake duct off the large rubber hose.

Carefully pull the intake duct off the top of the engine to release the three plastic pegs or "spikes" from their corresponding rubber grommets.

Release the smaller rubber hose on the underside of the intake duct by using the pliers to squeeze together the metal tabs on the hose clamp.

Four Ignition Coils

Push In Release Tab
Set the intake duct aside in a safe place.

Once the intake duct has been removed, you'll have easy access to the four ignition coils.

To help prevent from having debris or other objects fall down in to the engine, I recommend only checking or changing one spark plug at a time.

Push in the release button on the electrical connector before sliding it straight off the ignition coil.

Single Bolt Removed
Loosen the single bolt that secures the ignition coil to the valve cover by turning it in the counterclockwise direction with a 10mm socket and a 1/4" drive ratchet.

Set the bolt aside in a safe place.

OEM Part Number
Rotate the ignition coil back and forth a few times to make sure the rubber dust boot at the bottom is not stuck or "frozen" to the top of the old spark plug.

Lift the ignition coil straight out of the spark plug well.

If there is a CEL (check engine light) or SES (service engine soon) warning light displayed on your SUV's gauge cluster, use an OBDII scanner (also known as an "OBD2 scan tool") to check for an ignition coil related DTC (diagnostic trouble code) such as P0350, P0351, P0352, P0353 and P0354.

The OEM ignition coils are marked as part number Nissan 22448-1KC0A (22448 1KC0A 9Z23) or Hanshin XIC-BB20P L.

Loosen Counterclockwise
Attach the long extension bar (or two shorter extension bars) to the 14mm spark plug socket and a 3/8" drive ratchet.

If necessary, you could also use a 9/16" spark plug socket since 9/16" equals 14.2875mm.

Lower the socket into the well and over the top of the old spark plug.

Carefully loosen the old spark plug by turning it in the counterclockwise direction.

Try to avoid using excessive force to prevent from cracking the ceramic part of the old plug.

If you have trouble loosening the old spark plug due to corrosion (rust) or sand, spray a small amount of penetrating oil down into the well.

Allow the penetrating oil to seep into the threads for at least 10 to 15 minutes.

Spin Out Old Spark Plug

Lift Out Of Well

Inspect Old Spark Plug
Once the old spark plug is loose, detach the 3/8" drive ratchet and spin it out the rest of the way by hand.

Lift the old spark plug out of the well and detach it from the socket.

Inspect the old spark plug for any signs of damage or unusual wear.

If the old plug appears to be burnt or covered in soot and oily sludge, the engine might be burning oil and should be inspected by a professional mechanic.

If the electrode tip on appears to be burnt or covered in white powder, the engine may have been subjected to overheating and you may need to choose a spark plug with a different heat range (colder or hotter) for your climate.

The OEM (original equipment manufacturer) spark plug in this 2020 Rogue Sport was part number NGK DILKAR7D11H (90565).

The gap specification for the OEM plugs is 0.043" or 1.1mm.

If you have a spark plug gap gauge tool, check the gap on the new plugs.

Most spark plug manufacturers recommend that you do NOT use anti-seize lubricant grease on the threads of the new spark plugs since it can easily lead to over tightening.

Push the new spark plug into the socket.

Your socket should have a rubber insert or a strong magnet to hold the new plug in place.

Carefully lower the new plug down into the well.

Spin in the new spark plug by hand in the clockwise direction until it makes contact with the cylinder head.

If you have a very sensitive and reliable torque wrench, the torque specification in the service manual for tightening the spark plugs is 14 lb-ft (or 19.6 Nm).

Make sure the spark plugs are properly tightened before moving on to the next steps.

Push On To Spark Plug
Apply a small amount of dielectric grease to the opening in the rubber dust boot at the bottom of the ignition coil.

The dielectric grease will help ensure a reliable electrical connection by keeping out any moisture or debris.

Lower the ignition coil down into the spark plug well.

Push the rubber dust boot over the top of the new spark plug.

Spin in the ignition coil bolt a few turns by hand in the clockwise direction to make sure it doesn't become cross threaded.

Tighten the bolt by turning it in the clockwise direction with the 10mm socket and a 1/4" drive ratchet until it is snug.

Try to avoid over tightening the bolt to prevent from cracking the plastic ignition coil housing.

Slide the electrical connector straight on to the base of the ignition coil.

You should feel or hear the power plug "click" securely into place.

Push the intake duct down into place.

Make sure the intake duct is securely attached to the top of the engine.

Be sure to write down the spark plug change in your car's service records.

According to the maintenance schedule in the owner's manual, the iridium tipped OEM spark plugs should be replaced every 105,000 miles (or every 168,000 km).
