How to Change Lexus IS250 Spark Plugs | Broken Lexus Harness Plug Replacement

We change the dreaded spark plugs on the Lexus IS250 which requires removing the intake manifold for the last two plugs. We use OEM Denso spark plugs. Most of the plugs will break along the way, so we replace the brittle broken plugs with new OEM and aftermarket copies. This car uses 90919-01249 Denso (3473) FK20HBR11 Iridium (OEM Tri-tip). Only order from local autoparts, dealer, or Rock Auto. Don't trust Amazon sellers. There are alternatives to Denso which are Denso 4705 IKBH20TT Iridium TT Spark Plug. This might be slightly cheaper but minor gap difference. You can order these from dealers or from Japan from Amayama.
