Frequently Asked Questions
Will NGK 6418 fit a 1991-1995 Alfa Romeo 164?
That year, make, and model range appears in the exact application data. Confirm engine, required quantity, heat range, thread, reach, seat, and gap before ordering because trim and engine details are intentionally kept outside the YMM tag.
Should I check the gap on NGK 6418 before installation?
Yes. Verify the engine manufacturer's required gap before installation and use a suitable tool that will not damage a fine-wire electrode.
How many spark plugs are included with NGK 6418?
This listing includes 4 spark plugs. Confirm the engine's total required quantity before ordering.
Installation
Work on a cool engine with the battery isolated when required. Follow the vehicle and NGK procedures for part number 6418, compare the removed component before installation, use specified torque values, route wiring away from heat and moving parts, and verify normal operation before driving.
