Step-by-Step Instructions

Follow these steps carefully

Confirm engine and plug fitment

The OE plug is NGK ILZKAR8J8SY (stock #95660), a heat-range-8 laser-iridium plug that arrives pre-gapped at 0.030 in — buy 4. Do not attempt to re-gap the fine-wire iridium tips.

🔧 Mechanic's note — Ray Delgado

I've seen the aftermath when people skip this: Do not attempt to re-gap the fine-wire iridium tips. Don't learn it the expensive way.

Cool and expose the plugs

Let the 1.5T cool completely — the turbo sits close to the valve cover and holds heat. Disconnect the negative battery cable and lift off the engine cover.

Remove coils and clean wells

Release each coil connector, remove the coil bolt, and pull the coil straight up with a slow twist. Blow or brush every plug well clean before loosening anything — debris in these deep wells falls straight into the cylinder. Keep each coil with its cylinder.

Remove and install plugs

Remove the old plugs with a 14mm thin-wall spark-plug socket and long extension (a standard 5/8 in socket won't fit the M12 wells), comparing reach and electrode condition. Start each new ILZKAR8J8SY by hand and tighten to the manufacturer's spec in your owner's manual. No anti-seize on NGK's coated threads. Verify the pre-set 0.030 in gap without touching the tips.

Reconnect and verify

Reinstall the coils, bolts, and connectors, refit the cover and battery cable. Start the Integra and scan for misfires, then drive gently until warm before using boost. The 1.5T should idle smoothly and pull cleanly; any stutter under boost points to a coil boot that didn't seat fully.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Using the wrong plug or assuming a pre-gapped plug needs no verification
• Blowing debris into an open cylinder or plug well
• Cross-threading a plug or tightening it without a torque wrench
• Overusing anti-seize or dielectric grease on the plug threads
• Mixing coil connectors or ignoring a misfire after reassembly

Tools You'll Need

Metric/SAE socket set with extensions and swivel Spark-plug socket with rubber insert or magnet Torque wrench covering the plug range Compressed air or a soft brush, dielectric grease, gloves, and eye protection 14mm thin-wall spark-plug socket with rubber insert

⚠️ Safety First!

• Informational DIY. EZ Car Fix is not a shop.
• Work on a cool engine and keep dirt out of the plug wells.
• Verify plug type, gap, reach, and torque in the exact service information; do not rely on a generic value.
• Do not pull on coil wiring, cross-thread plugs, or use an impact gun for installation.
• Stop if a plug is seized, the threads are damaged, or fuel/oil contamination indicates a larger fault. Spark-plug service is for an internal-combustion engine only; never apply it to an EV or Tesla.
