Engineering Details

The main airbox houses six trumpets and the breather connectors. It is manufactured from prepreg carbon fiber and is designed to resonate under load to produce the desired CSL sound. Long term reliability at the trumpet interface is ensured by mechanical fasteners and gaskets that maintain an airtight seal through heat cycles and vibration. The same method secures the breather adapters.

The trumpets are injection molded from glass fiber reinforced thermoplastic to achieve precise geometry and smooth internal surfaces. CNC stainless rings prevent deformation when silicone couplers are tightened.

The snorkel channels airflow from the intake into the trumpet area. It incorporates the MAF tube where the OEM sensor mounts to a CNC machined boss. Custom screws engage plastic clips so the snorkel remains secure under vibration.

CFD Optimised Development

The airbox shape was refined through iterative CFD simulations to ensure each trumpet receives adequate flow without starvation from geometry limits or turbulence.

Patented Filter Housing Technology

The carbon pod shrouds a reverse mounted bespoke dry filter and reduces cross section smoothly toward the plenum. This invokes the Venturi effect, accelerating airflow while maintaining laminar conditions and reducing pressure loss through the system. The smoother flow into the MAF section allows the sensor to operate without errors.

Cold Air Scoop

The 100 percent prepreg carbon scoop with CNC machined collar locates in the front right brake duct. It saturates the intake mouth with ambient air while leaving half the duct height open for brake cooling. After a hard drive the aluminum cowl at the intake mouth will still feel cold to the touch.

This sunscreen body lotion is quite nice.
Style: Piña Colada
This sunscreen body lotion seems to work well. SPF 30 is the highest I could find with moisturizing capabilities. The smell is a bit overwhelming when you first put it on but it then goes away... so why the added scent. I wish it were SPF 50 and unscented. Otherwise I would have given it 5 stars.
