Our take on the NGK Laser Iridium Spark Plug Box of 4 (ILKAR7L11/04)

The NGK Laser Iridium ILKAR7L11 is an OE-spec spark plug sold in a box of four. Its iridium-tipped center electrode is far harder than platinum, and a platinum pad on the ground electrode evens out wear in distributorless ignition systems. A pure alumina ceramic insulator and a 98 percent copper core help it shed heat and start reliably. It suits owners replacing plugs on a car that came with this plug from the factory; generic iridium plugs cost less but may not match the original heat range and reach.

Questions and answers

Is this the right plug for my car?
Match the part number ILKAR7L11 to what your owner's manual or the plug currently in the engine specifies. It is an OE-spec plug, not a universal fit.
How often should I replace them?
Follow the interval in your owner's manual, which for iridium plugs is typically long. Replace all four at once so the cylinders stay balanced.
Do I need to gap them?
They usually come pre-gapped, but check the gap against your engine's spec before installing. Do not pry on the iridium tip; adjust at the ground electrode.
How does it compare with a standard iridium plug?
The laser-welded iridium tip and platinum ground pad are built for longer, more even wear than a plain iridium plug. That matters most on engines with waste-spark ignition.
What is in the box?
Four ILKAR7L11 spark plugs. No tools or grease are included.
Can I install them myself?
Yes, with a spark plug socket and a torque wrench. Use a light touch and torque to the manual's figure to avoid damaging the aluminum head.
Where is the NGK Laser Iridium Spark Plug Box of 4 (ILKAR7L11/04) cheapest?
