NGK XR45 spark plug for the 1975-1976 Oldsmobile Cutlass Salon V8 7.5L, the 1975-1977 Cutlass Salon V8 5.7L, the 1975-1980 Cutlass Salon V8 4.3L, the 1977 Cutlass Salon V8 6.6L, the 1979 Cutlass Salon V8 5.7L and other vehicles fires the spark that ignites the air-fuel mixture in one cylinder. It is one of the NGK spark plugs in the V-Power line, engineered for OE applications.
- NGK V-Power line with a V-cut nickel alloy center electrode and a concave ground electrode for ignitability
- High grade alumina silicate ceramic insulator for dielectric performance
- Trivalent metal plating gives anti-corrosion and anti-seizing properties for easier installation and removal
- Solid copper core of 98% pure copper for heat dissipation, conductivity and wide heat ranges
- Cold-rolled threads that prevent cross-threading and damage to cylinder heads
Quick facts
- Part: NGK XR45 spark plug
- Fits: the 1975-1976 Oldsmobile Cutlass Salon V8 7.5L, the 1975-1977 Cutlass Salon V8 5.7L, the 1975-1980 Cutlass Salon V8 4.3L, the 1977 Cutlass Salon V8 6.6L, the 1979 Cutlass Salon V8 5.7L and other vehicles
- Condition: New
A worn spark plug can show up as hard starting, a rough idle or a misfire. These signs alone do not prove the plug is the problem, since a weak ignition coil can also give a rough idle.
Fits
The plug is listed for a wide range of Oldsmobile, Buick, Pontiac and Cadillac models, among them the 1973-1976 Oldsmobile Cutlass Supreme V8 7.5L, the 1975-1977 Cutlass Supreme V8 5.7L, the 1975-1982 Cutlass Supreme V8 4.3L, the 1977 Cutlass Supreme V8 6.6L, the 1979-1980 Cutlass Supreme V8 5.7L and the 1982-1984 Cutlass Supreme V8 5.0L. The V8 engines take one plug per cylinder, eight in all, and the V6-3.8L takes six. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is the NGK XR45 spark plug right for a 1975-1976 Oldsmobile Cutlass Salon V8 7.5L?
Yes. The NGK XR45 is listed for the 1975-1976 Oldsmobile Cutlass Salon V8 7.5L, which takes eight plugs, one per cylinder.
What thread size does the NGK XR45 spark plug have?
The NGK XR45 has an M14 - 1.25 thread and a 13/16 in hex.
Does this V-Power plug have a copper core?
Yes. It has a solid copper core of 98% pure copper for heat dissipation, conductivity and wide heat ranges.
Can I use V-Power plugs where the factory plugs are precious metal?
No, it is not recommended there. This plug is best for vehicles with OE nickel alloy plugs, not for vehicles with factory precious metal plugs.
What do the cold-rolled threads on this spark plug do?
The cold-rolled threads prevent cross-threading and damage to cylinder heads. Trivalent metal plating adds anti-seizing properties for easier removal.
