Key Lexus Parts That Keep the LX450 Performing as It Should

Strong reliability and off-road capability made the Lexus LX450 a standout when it launched in 1996. It continues to attract drivers who want a full-size SUV that can handle rugged terrain without giving up comfort. Many LX450 owners drive theirs well past 200,000 miles, but regular part replacement makes a difference. Using genuine Lexus parts from Longo Lexus helps prevent the early wear that often comes with cheaper aftermarket options.

Keep engine performance consistent with a clean air filter

The engine air filter protects the LX450’s inline-six by keeping dust and debris out of the combustion chamber. In high-mileage vehicles or those used in dusty areas, clogged filters can cause slow acceleration or poor fuel economy. Most owners change them every 15,000 to 30,000 miles, depending on driving conditions. A genuine Lexus air filter fits better and traps more dirt than generic brands, which may allow particles through or restrict airflow.

Don’t skip worn spark plugs during regular service

The LX450 relies on high-quality spark plugs to keep ignition smooth. Over time, plugs lose their ability to fire efficiently, especially after 60,000 miles or more. Misfires, rough idling, and lower fuel economy are common signs they’re overdue. Genuine Lexus plugs are matched to the engine’s original specs, while lower-cost alternatives tend to wear faster or affect engine timing.

Replace oxygen sensors to improve fuel balance

Located in the exhaust system, the oxygen sensor helps the LX450 adjust its air-fuel ratio. Faulty sensors lead to rough running or sudden dips in fuel economy, especially in older models. Lexus recommends checking them around 100,000 miles or sooner if the check engine light comes on. Genuine Lexus sensors work more accurately and last longer than aftermarket versions, which often trigger false readings or early failure.

The Lexus LX450 is known for long-term durability, but even it needs the right parts to stay dependable. Genuine parts from Longo Lexus offer a clear edge in fit, quality, and performance. Aftermarket shortcuts often bring problems that cost more down the road. Replacing common parts on time with Lexus-built components is the best way to keep the LX450 going strong.
