DIY spark plug replacement on Tundra, Tacoma, 4Runner, and Fj Cruiser for the 1GRFE 4.0L V6.

The 1GRFE is the 4.0 L (3956 cc) version, designed for longitudinal mounting in RWD and 4WD pickup applications. It has a 94 mm bore and a stroke of 95 mm. Output is 236 hp (176 kW) at 5200 rpm with 266 lb⋅ft (361 N⋅m) of torque at 4000 rpm on 87 octane, and 240 hp (179 kW) at 5200 rpm with 278 lb⋅ft (377 N⋅m) at 3700 rpm on 91 octane. This engine features Toyota's VVTi, variable valve timing system on the intake cam and a compression ratio of 10.0:1. Service weight, including fluids, is 166 kg (366 lb).

An updated version of this engine features Dual VVTi, increasing output to 270 hp (201 kW) at 5600 rpm and 278 lb⋅ft (377 N⋅m) at 4400 rpm on 87 octane and 285 hp (213 kW) and 289 lb⋅ft (392 N⋅m) on 91 octane.[citation needed] Inside, the 1GR uses a "tapersquish" combustion chamber design with matching pistons to improve antiknocking and engine performance, while also improving intake and fuel efficiency. Toyota adopted a siamesetype intake port, which reduces the surface area of the port walls and prevents fuel from adhering to such walls. This engine has special castiron cylinder liners cast into the block, which are a spiny type to improve adhesion between the liner and cylinder block. With these special thin liners it is impossible to bore the block. In the event of cylinder wall damage (scoring, deep protrusions, etc.), the entire cylinder block must be replaced. For increased block rigidity, the 1GR also receives a high temperature plastic insulator/protector, which fills the empty space between the outer portion of the cylinders and block material common to open deck engines. For increased cooling efficiency, the 1GR employs water passages between the bores of the engine. There are two such passages for each bank for a total of four. This reduces cylinder hotspotting and keeps combustion chamber temperatures more uniform.

A bolton TRD supercharger kit was available on the Tacoma and FJ Cruiser but has been discontinued by Toyota.

The new 2015 Toyota HiLux receives a slightly different version of the single VVTi engine, with the only change being a removal of an air intake baffle tank being replaced by a conventional air filter housing to intake pipe to surge tank style. The new intake pipe now contains resonators. Power output is unchanged.
