I agree probably feel the same but any diff in stats. Reason I ask is an intake adds about 5 hp /torque. If there’s no difference with 5 hp/torque then I’m thinking to save my 300 dollars

The 2GR-FKS combines the D-4S system from the 2GR-FSE with the simulated on-demand Atkinson cycle used in the 2UR-GSE and 8AR-FTS engines. The intake camshafts are equipped with VVT-iW and the exhaust camshafts are equipped with VVT-i. In the Tacoma the engine specifications are 207 kW (278 hp) at 6000 rpm and 359 N⋅m (265 lb⋅ft) at 4600 rpm.[9] In the Lexus RX 350 the engine specifications are 220 kW (295 hp) at 6300 rpm and 362 N⋅m (267 lb⋅ft) at 4700 rpm respectively. In the Lexus IS350 and GS350 the engine specifications are 232 kW (311 hp) at 6600 rpm and 380 N⋅m (280 lb⋅ft) at 4800 rpm respectively.
The 2GR-FSE is a 3.5L engine used in the Lexus IS, GS 350, Mark X and Crown and incorporates Toyota's latest D-4S twin injection fuel system. This system combines direct injection (949cc/min injectors) with traditional port injection (298cc/min injectors). Direct injection lowers the tendency to knock (detonation) and increases performance by reducing the charge intake temperature. Traditionally, direct injection engines require an in-engine mechanism such as swirl ports or specific piston crown shapes to increase air turbulence in the engine. These are in place to help achieve a homogeneous air-fuel mixture inside the cylinder at low RPM and high load, but these mechanisms inhibit performance at higher engine speeds. In the 2GR-FSE, port injection is used considerably to achieve the correct mixture without having in-engine restrictions, meaning the engine achieves specific power near the top of all naturally aspirated production gasoline engines in the world (67 kW/L, 235 kW in the Mark X). Toyota also developed a new type of injector for this engine. The dual fan spray pattern of the direct injectors is perpendicular to the piston travel with wide dispersion in the cylinder, which aids air and fuel mixture and therefore increases power and efficiency. The port injectors not only help improve the power and efficiency but they also help improve emissions, especially in the first 20 seconds after start-up (when the catalytic converter is in its warm-up stage). Compression ratio is 11.8:1.
The 2GR-FSE engine is rated at 309 PS (227 kW; 305 hp) at 6,400 RPM and 38.4 kg⋅m (377 N⋅m; 278 lb⋅ft) at 4,800 RPM.

LSD is optional, they brought back the Adaptive headlight, Standard some old features like steering wheel Tele. BSM memory seat, radar cruise control , lane change etc, add new feature like apple car play, the Engine parts gets update once in awhile. The 2GR-FKS released for Lexus GS350 - RX350 and Toyota Tacoma/Highlander in 2015 , as of now 2018 Toyota Camry XSE and Sienna using same tech Engine like IS350 but only make 301 HP , the 2018 XSE Camry is fast !
