2016 Tesla Model X Spark Plug Specs: Type, Gap & Torque Guide

As an ASE-certified master technician, I hear a lot of interesting questions in the shop, and looking up ignition specs for electric vehicles is a surprisingly common one! If you are searching for the spark plug type, gap, torque specs, and replacement intervals for a 2016 Tesla Model X, I have some fantastic news for your wallet and your weekend schedule: your vehicle doesn't have any spark plugs.

The 2016 Tesla Model X (whether you have the 75D, 90D, or P90D) is a Battery Electric Vehicle (BEV). Because it is powered entirely by high-voltage battery packs and electric motors rather than an internal combustion engine (ICE), it has no cylinders, no fuel to ignite, and therefore, absolutely zero spark plugs or ignition coils.

However, to keep with our standard Repairius format—and just in case you are trying to win a bet with a buddy—here is the official spec breakdown.

Quick reference

Why the right plug matters (And why you don't need them)

In a traditional gas-powered vehicle, selecting the right spark plug is critical. You have to consider the heat range to prevent pre-ignition, and choose between electrode metals like copper, platinum, and iridium. Iridium plugs, for example, can last over 100,000 miles due to their hardness, while traditional copper plugs might need replacing every 30,000 miles.

In your Tesla Model X, propulsion is handled by an inverter that converts DC power from the battery into AC power. This AC power creates a rotating magnetic field in the motor's stator, which pulls the rotor along with it to turn the wheels. No fuel is compressed, and no spark is needed to create an explosion. The "right plug" for a Tesla is the charging plug you use in your garage!

How to gap a spark plug

Since you don't have spark plugs to gap on your Model X, you get to skip this step entirely! But if you happen to have a gas-powered daily driver or a classic car sitting next to the Tesla in your garage, the rule of thumb remains the same: always verify the gap before installation.

Using a proper wire-style gauge tool or a feeler gauge, gently measure the distance between the center and ground electrode. If the gap is too tight, use the tool to apply a light bend to the ground electrode to open it up. If it's too wide, lightly tap the ground electrode on a soft workbench. Never pry against the delicate center electrode, especially on iridium plugs, as the tip can snap right off.

Replacement procedure tips

You won't be dealing with the anti-seize debate, struggling with stubborn coil-on-plug boots, or applying dielectric grease on your Model X. However, your EV still requires routine maintenance to stay safe and reliable on the road.

Instead of an ignition tune-up, your 2016 Model X maintenance interval should focus on:

• Cabin Air Filter: Replace every 2 years to keep your HVAC system smelling fresh.
• HEPA Filter: If equipped with the Bioweapon Defense Mode, replace the HEPA filter every 3 years.
• Brake Fluid: Test for moisture contamination every 2 years and replace as necessary. (EVs use regenerative braking, so the mechanical brakes are used less often, making fluid checks even more critical to prevent caliper seizing).
• Tires: Rotate every 6,250 miles or if tread depth difference is 2/32 in or greater. The heavy weight and immense torque of the Model X eat through tires much faster than a standard gas SUV.

Known issues

Many gas engines have notorious ignition problems—like the infamous Ford 3-valve 2-piece spark plug breakage, or GM 5.3 ionization-sensing coil failures.

Fortunately, the 2016 Model X suffers from none of these traditional ignition woes. You will never have to worry about a cracked porcelain insulator causing a misfire under load, or a blown-out spark plug shell thread taking out your cylinder head. Your primary concerns with the 2016 Model X will largely revolve around suspension wear (half-shaft shudder under hard acceleration) and maintaining the intricate falcon-wing doors, rather than anything under the hood.
