NGK 2526 spark plug for the 1999-2004 Toyota Tacoma 4-cylinder 2.4L or 2.7L and other vehicles fires the spark that ignites the air-fuel mixture in each cylinder. Among NGK spark plugs, the V-Power line improves ignitability over standard nickel plugs.
- NGK V-Power line with a V-cut nickel alloy center electrode and a concave ground electrode for quicker starts and smoother idle
- Trivalent metal plating for anti-corrosion and anti-seizing properties, which eases installation and removal
- High grade alumina silicate ceramic insulator for dielectric performance
- 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 2526 spark plug
- Fits: 1999-2004 Toyota Tacoma 4-cylinder 2.4L or 2.7L and other vehicles
- Condition: New
A worn plug can show up as a hard start, a rough idle or hesitation, but a coil, wire or fuel problem can produce those symptoms too, so find the cause before you swap plugs. With the engine off and cool, you can look at the electrode for wear or deposits and the ceramic for cracks. The engine takes one plug on each cylinder.
Fits
It is also a spark plug for the 2000 Toyota 4Runner 4-cylinder 2.7L and the 2015-2017 Toyota Yaris 4-cylinder 1.5L.
