Owners of other Nissan vehicle such as the Sentra, Altima, Maxima, Murano, Rogue,  Note, Leaf, Juke, Kicks, Latio, Almera, Sunny, Qashqai, NV200, Pathfinder, Frontier and X-Trail may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) platinum tipped spark plugs in this 2019 Nissan Versa SV with the HR16DE 1.6L I4 engine were part number NGK PLZKAR6A-11 (5118).

Please verify the correct part number for your vehicle before purchasing new spark plugs.

The tools and other items needed to complete this procedure include a 14mm spark plug socket, an extension bar, a 3/8" drive ratchet, a standard flat head screwdriver, needle nose pliers, a 10mm socket with an extension bar, a 1/4" drive ratchet and a tube of dielectric grease.

An optional item is anti-seize lubricant. Most spark plug manufacturers recommend that you do NOT use anti-seize since it can easily lead to over tightening.

Since this 2019 Versa only has about 15,000 miles on the odometer, I'll just be checking and replacing the one exposed spark plug on the right (driver) side of the engine.

I've included written instructions for removing the intake manifold in order to access all four spark plugs.

Make sure the engine is completely cool or cold before continuing. Do not attempt this procedure on a hot engine!

In order to remove the intake manifold, you'll have to loosen the hose clamp that attaches the large rubber air intake hose from the engine air filter box to the throttle body by turning it in the counterclockwise direction with the flat head screwdriver or an 8mm socket with a 1/4" drive ratchet.

Pull large rubber hose off the throttle body.

Disconnect the air vacuum hoses from the intake manifold including the PCV valve hose on the left (passenger) side and the one attached to the engine air filter housing on the right. There are two hoses on the left (passenger) side.

You'll need to use pliers to squeeze together the two tabs on the metal hose clamp before sliding it away from the nipple on the intake manifold before pulling the rubber hose straight off.

To disconnect the wire loom from the intake manifold, pinch together the two tabs or "prongs" on the black plastic retaining clip before sliding it straight out of the hole.

Disconnect the electrical connectors on the throttle body.

Remove the 10mm bolt on the left (passenger) side by the rear corner of the intake manifold (mounted vertically - up and down).

Remove the 10mm bolt on the right (driver) side by the rear corner of the intake manifold by the throttle body (mounted vertically - up and down).

Remove the five 10mm bolts on the front edge of the intake manifold (close to the front of the car) by turning them in the counterclockwise direction. The front five bolts are mounted horizontally (front of the car to the rear of the car).

Carefully remove the two coolant hoses near the bottom of the throttle body. A small amount of coolant may leak out. Try to keep the ends of the hoses pointing up.

Remove the dipstick for more clearance and set it aside in a safe place.

Carefully lift the intake manifold assembly off the top of the engine and set it aside in a safe place.

To help prevent from having debris or foreign objects fall down into the spark plug well or cylinder, I recommend only checking or changing one spark plug at a time.

Push down the release tab on the electrical connector before sliding it straight off the ignition coil.

I had trouble pushing down the release button, so I used some pliers to squeeze the release tab.

Set the bolt aside in a safe place.

Gently rotate the ignition coil back and forth a few times to help make sure the rubber dust boot at the bottom isn't stuck or "frozen" to the top of the old spark plug.

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

The OEM ignition coils are marked as part number Hitachi Hanshin AIC-9408N 22448 5RBOA 9410.

A compatible replacement set of aftermarket ignition coils are part number TRQ ICA64416.

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

(A 9/16" spark plug socket would also work if that's all you have available.)

Lower the socket over the top of the old spark plug.

Loosen the old spark plug by turning it in the counterclockwise direction.

If you have trouble loosening the old spark plug due to corrosion (rust) or debris, try spraying a very small amount of penetrating oil down into the spark plug and wait ten to fifteen minutes.

Carefully 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 excessive wear.

If the old plug appears to be burnt or covered in soot and oily sludge, the engine may 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 might 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 NGK PLZKAR6A-11 (5118) spark plugs should have a gap of .043" (1.1mm) according to the manufacturer and the shop manual.

Push the new spark plug into your socket. Your socket should have a rubber insert or a strong magnet to securely hold the spark plug in place.

Carefully lower the new plug down into the well. Try to avoid hitting the electrode tip against the sides of the well or the top of the cylinder head.

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

If you are installing a new spark plug, continue tightening it in the clockwise direction with the 3/8" drive ratchet to just past the point when you feel the new crush washer collapse. This should be about 3/8 to 1/2 turn past when the spark plug first makes contact with the cylinder head.

If you have a very sensitive and reliable torque wrench, the service manual for the 2017 Nissan Versa lists a torque specification of 14 lb-ft or 19.6 N-m for tightening the spark plugs.

I recommend that you do NOT use anti-seize lubricant grease since it can easily lead to over tightening.

If you are just re-installing the old spark plug after checking it, you will only need to tighten it a small fraction of a turn past finger tight until it is snug.

Avoid over tightening the spark plugs to prevent from cracking the ceramic or damaging the aluminum threads.

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 keep out any moisture, dust or debris and ensure a reliable electrical connection.

Line up the bolt hole in the ignition coil with the corresponding bolt hole in the valve cover.

Spin in the 10mm bolt a few turns by hand to help prevent it from becoming cross threaded.

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

The torque specification in the 2017 Nissan Versa service manual for tightening the 10mm ignition coil bolt is just 62 in-lb or 7 N-m.

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

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

Double check that the bolts and electrical connectors are securely attached.

Replace the intake manifold, re-attach the throttle body hoses and connect the power plugs.

Double check that every rubber hose is securely re-attached and every electrical connector has been replaced.

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

The service interval specification in the owner's manual is to change the platinum tipped spark plugs at least every 105,000 miles or every 168,000 km.
