Crucial field experience & common DIY pitfalls to avoid on the 2014 - 2023 Lexus IS 350 / IS 300 V6
Curing Aggressive Front Inner Tire Wear: LCA Bushing Upgrade
A notorious trait of 3rd Gen IS models is severe premature wear on the inside edges of the front tires, even when alignment is within factory spec. This occurs because the factory rear-most front Lower Control Arm (LCA) rubber bushings are too soft and deflect backwards under braking. Replacing them with stiffer Lexus RC F / GS F OEM bushings (Part # 48075-24010 & 48076-24010) permanently eliminates dynamic toe-out deflection and triples front tire lifespan.
Rear Spark Plug Bank 1 Access with Strut Braces
On the longitudinal 2GR V6 in the IS 350, Cylinders #5 and #6 at the rear of the engine bay are obstructed by factory strut tower brace bars and wiring harnesses. You do not need to dismantle the strut bars; use a 5/8-inch magnetic wobble extension socket to snake into the plug tubes at an angle.
D-4S High-Pressure Fuel Pump Ticking: Normal vs Faulty
The D-4S system operates mechanical direct-injection fuel pumps driven by the exhaust camshaft, producing a rhythmic, sharp ticking sound at idle (often mistaken by owners for valvetrain noise or rod knock). This is 100% normal. The noise only indicates a fault if accompanied by long cranking times or low fuel rail pressure codes (P0087).

❓ Frequently Asked Questions
How much oil does an IS 350 take?
With a new oil filter, the Lexus IS 350 (3.5L V6 2GR-FSE / 2GR-FKS) takes 6.8 US quarts (6.4 liters) for RWD models and 6.7 US quarts (6.3 liters) for AWD models using SAE 0W-20 full synthetic engine oil.
Why do Lexus IS 350 front tires wear out so fast on the inside?
Factory rear lower control arm (LCA) bushings are engineered soft for ride comfort. Under braking, compliance in the rubber causes the wheels to toe out dynamically, dragging the inner shoulder of the front tires. Installing stiffer RC F / GS F OEM bushings permanently cures this issue.
What is the spark plug change interval for the 3rd Gen IS 350?
Lexus mandates spark plug replacement every 60,000 miles (96,000 km) for the direct-injected D-4S 2GR engine using Denso FK20HBR11 spark plugs.
