A known failure. A proven fix.
Intake manifold rod failure in the 997 GT3 RS is a well-documented issue that can lead to catastrophic damage to the Mezger engine—often resulting in a full engine replacement, with costs exceeding $80,000.
This retrofit kit was developed specifically to eliminate that failure mode, using a rigorous, engineering-first process focused on long-term durability and mechanical resilience.
To ensure unmatched reliability, we followed a three-stage engineering process:
Geometry Redesign: Eliminated stress concentrators found in the original design
Material upgrades: Aerospace-grade 17-4PH stainless steel rods and ULTEM 1000 flaps, a high-performance thermoplastic utilized in aerospace applications.
Structural Reinforcement: Increased rod diameter by 25% for superior fatigue resistance
This kit has undergone extensive real-world testing in our own 997.2 GT3 RS, across both street driving and multiple track days.
Two precision-machined intake manifold rods and flaps
New Iglide bushings for a clean install into the OEM aluminum Intake housing
No cutting, welding, or manifold modification required
Detailed installation instructions
Crafted with care and technical rigor in the Pacific Northwest, this solution is for owners who refuse to compromise.
