Lexus Block Heaters

Which heater fits your Lexus?

Start with your model, year and engine below. There is no single Lexus block heater: a matching engine size or an Amazon listing title does not establish fitment.

• Early IS 300, 3.0L: the 2001–2004 2JZ engine cross-reference points to Kat's 11401, a 40 mm frost-plug heater. Our cited catalog stops at 2004; 2005 remains unconfirmed. Check IS 300 year and engine →
• Later IS models: Lexus lists different 2.0L turbo and 3.5L V6 powertrains. Do not carry the early 3.0L heater number forward. Lexus engine reference ↗
• Already have a heater? Identify its maker and connector before buying a replacement cord. A Kat's cord is not automatically a replacement for a factory-installed Lexus heater. Identify the cord →

Checked Canada/U.S. Amazon buying options appear on the selected part. Where exact fitment or a listing is unconfirmed, the page says so. Kat's catalog, Lexus table, printed page 13 ↗
