Installation Notes and Tips

Verify the connector style, terminal count, and mounting location before installation. Confirm whether your vehicle uses the intake, left, or right position listed for your exact year and engine configuration. For 2008 Lexus GS350, GS450h, IS250, and IS350 applications, note the fitment cutoff to 02/2008 where specified.
