I-Rotary Apex seals – 13B Silver set

Now also available in the following sizes :

• 12A
• 13B 2mm
• 13B 3mm
• Renesis / Rx8

The Silver Series I-Rotary Apex Seal has been developed for the perfect balance of quality, ultimate performance and cost regardless of the engine application from low power normally aspirated engines to high horsepower “Drag” race engines.
The Silver Series is made using newly developed proprietary advanced manufacturing processes that retain many of the qualities of the Gold Series I-Rotary Apex Seal at less cost.
The Silver Series material is made from the same custom base material used in the manufacture of the Gold Series, but which is processed differently to reduce cost. This material has very consistent material properties, excellent strength at temperature, a very low level of friction and wear as well as an excellent performance level against the rotor housing chrome surface.
The material qualities and consistency of the Silver Series I-Rotary Apex Seal are superior to all other available apex seals on the market except for the Gold Series I-Rotary Apex Seal.
The Silver Series accuracy and precision is unsurpassed by any other metallic apex seal except for the Gold Series I-Rotary Apex Seal.
This level of accuracy, precision and consistency is achieved through the use of proprietary processes that have allowed the larger volume manufacture of the Silver Series I-Rotary Apex Seal.

Features of the I-Rotary Metallic Apex Seal
Custom material properties designed for strength, toughness, high temperature exposure, low wear and kindness to the rotor housing.
Extensive testing performed during all phases of production to ensure consistent material properties so that maximum performance with the lowest wear is achieved.
High level of accuracy and precision with every I-Rotary Apex Seal inspected multiple times throughout the manufacturing process to provide dimensional consistency from set to set.
Ideal applications include supercharged, turbocharged or nitrous oxide engines for road racing, drifting, time attack and drag racing cars.

Benefits of the I-Rotary Metallic Apex Seal
The consistent material properties and dimensions of the I-Rotary Apex Seal:
Predictable engine tuning and performance from seal set to seal set
Practically eliminates the need to custom fit each rotor groove to the apex seal, as is usually required with most other products. This means that a lot less time is spent during assembly.  It is just like installing a set of stock Mazda apex seals.
Reproducible engine break in period.
Faster engine starts – similar to an engine using stock Mazda apex seals.
Reduced fuel use due to better sealing performance – less wasted fuel coming out of the tail pipe.
And most importantly, more horsepower due to better sealing compression at high RPM.
