Can You Tune a Lexus RX 350?

Your RX350 is the quintessential Lexus luxury SUV -- one at once capable, enviably comfortable, and expertly equipped. One more affordable than most BMW X5 and Acura MDX models, too. It's got everything going for it.

That means upgrade prospects, too. Tuning the engine computer for performance, for instance, can be done pretty easily through the car's OBD-II (Onboard Diagnostics II) port, a 16-pin port you can usually find under the dash on the driver's side. All you'll need is a specialized advanced scan tool.

The thing is, you shouldn't do that, under any circumstances.

That's because using a tool for tuning that only certified Lexus mechanics should use to troubleshoot error codes and figure out repairs can void your car's warranty. There are easier (and better -- and safer) ways to get the power bump, higher efficiency, and nimbler handling you want. Here's just a few of them; consider them for your next project instead.

  • Install a turbocharger or upgrade to a supercharger. One can allow a lot more air into the engine.
  • Make the most of that air intake: swap out the stock induction system for a cold air intake -- in other words, relocate the factory engine air filter to above a wheel well or near a fender: a spot outside the engine compartment where it can pull in cooler, denser, ad higher-quality air. Also, update the exhaust system: relieve backpressure by opening up the exhaust pipe.
  • Get cleaner air, and more of it than usual -- replace that engine filter with a performance air filter.
  • Of course, there's plenty else you can do. Just be sure to choose genuine OEM parts for the job -- everything, right down to the replacement spark plugs and brake pads. OEM accessories, too -- even things like all-weather floor mats and seat covers. They're the only ones guaranteed to be top-quality and to fit, after all -- not to mention to come with warranty coverage on top of your own.
