This kit replaces the factory post-MAF air intake hose on the 2001-2005 Lexus IS300 (XE10, 2JZ-GE) with a black wire-reinforced silicone hose rated to 347°F. The original rubber hose hardens, cracks and collapses with age, and any split downstream of the mass airflow sensor lets in unmetered air, upsetting fuelling and idle. The silicone replacement holds its shape under vacuum and shrugs off the underhood heat cycling that kills the stock part.
The hose is built from five plies of silicone with heat-resistant reinforcing fibres and an embedded support wire, and it carries an anodized CNC-machined CCV port so the factory crankcase ventilation line reconnects without an adapter. It is a direct fit in the stock location, no cutting, no fabrication. The box contains one hose and two stainless steel T-bolt clamps; this is a single-hose kit, not a full coolant or turbo hose set, and it does not include a filter or intake tube. Backed by the Mishimoto Lifetime Warranty. Wire-reinforced 5-layer silicone with heat-resistant fibres. Maximum operating temperature 347°F. Replaces the worn, cracked or collapsed factory post-MAF intake hose. Fits the 2001-2005 Lexus IS300 with the 2JZ-GE inline-six (XE10 chassis).
