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.

Rough dial, pretty watch
Color: Mesh Strap watch balck
Great looking watch, the dial is rough on the skin, it should be refined some to not have sharp edges.

Great Watch for a Great Price
Color: Dark Brown band & Rose Gold bezel & Navy Blue dial
⌚ “Simple, clean, and gets compliments every time.” ⌚ This Watch has easily become my go-to watch. What I like most is how clean the design is. It’s not flashy, but it stands out in a classy way. I usually pair it with brown shoes and a belt, and it pulls the whole look together perfectly. Another big plus—it doesn’t feel heavy on the wrist. You can wear it all day and forget it’s even there, which is exactly what you want in a daily watch. And the compliments? They come consistently. It’s one of those pieces people notice without you trying too hard. ✔️ Clean, stylish design ✔️ Lightweight and comfortable ✔️ Pairs perfectly with dress or casual outfits ✔️ Gets a lot of compliments If you’re looking for an affordable watch that looks sharp and feels great, this is a solid choice.

Unusable Adjustment Diagram – Completely Black
Color: Mesh Strap watch silver balck
The watch itself looks nice, but there is an issue with the instructions for adjusting the band. The included diagram is completely black and does not show how to make the adjustment. I was only able to adjust the band because I had a diagram from a previous watch. Without that, it would have been very difficult. The manufacturer should provide clear and readable instructions.

You won’t be disappointed with this one
Color: All Golden face Big Dial
Looks great fits great I was skeptical about getting it because I purchased another variation and was not happy at all but I like the way that this one looks so I said I’d give it another shot. I’m glad I did. I’m very impressed with it.

Stunning Automatic Watch With TopTier Durability and Precision
Color: Grey
“I got this Tissot PRX for my cousin’s birthday and bro fell in LOVE instantly. This thing keeps time like a beast, never slows down, never lags. Automatic movement, so no batteries, no drama. Durability? Stupid good. You can hit it, bump it, live life rough, it still looks box fresh. Size wise it was almost perfect. I just had to remove two links, nothing big. It’s light, functional, comfortable, doesn’t weigh you down, doesn’t get in the way but more importantly I can say this watch is in everyone’s eyesight when we wear it. Cause of course I had to get another one! Basically. I gave him a very nice piece as a gift, and now he’s walking around like he owns Switzerland.
