Description

Compressive Tuning is proud to introduce into it’s product lineup, Airblade: Heat Extractors. Not only are the Airblades functional but they bring your engine bay look to a whole new level.

Handmade by our team, we use light-weight aluminum with a precision cut that ventilates the engine bay, promoting good exhaust of airflow away from your engine and out through the wheel wells.

Improve your engine bay aesthetics and make your engine bay stand out of your fellow enthusiasts with the Compressive Tuning Air Blade Engine Bay Vents!

The blades that promote even temperatures and airflow through your engine bay, while giving your Subaru an outstanding visual upgrade.

The sleek design of the shrouds will totally change the look of your engine bay, especially combined with the Compressive Tuning Smartflow Shroud offerings for your 2015+ WRX/STI.

Along with the great design you'll see the added benefit of heat extraction through the engine bay vent as air passes over the engine and exits the shroud.

DETAILS

  • Made by 1mm thick premium industrial aluminum for light weight and durability
  • Superior fitment with hand-made welding process
  • Iconic Shark Fin design on the heat extracting holes for better aerodynamic
  • Industrial laser cutting for unique beehive design and maximum heat extracting efficiency.

FITMENTS AND CLEARANCE

In order to make the airblade could fit like the stock piece, weeks were spent on the measurement and prototyping. The easiest way is to make the whole thing shorter, but there would be a big section left empty if doing so, so Compressive Tuning decided to take up the challenge and make the Airblade long enough to cover the area that were covered by the stock piece.

In order to get the right angle, and make sure it could fit like a glove, multiple pieces were made for testing. After weeks of work, Compressive Tuning finally made it right, and the most difficult part of the design was complete.

HEAT EXTRACTION AND PATTERN

The major feature of the Airblade is heat extraction, so one of the most important thing is to make sure that the heat could be extracted in the quickest way while we keep the aggressive design of the product. Multiple pattern design were tested to find the best result.

SHARK FIN

The shark fin is the major design point of the Airblade, but it’s not just for looks, but also a result with consideration of the air flow. And also, Compressive Tuning didn’t want the inner side of fender to be exposed, won’t look good, so the shark fin was the design Compressive Tuning went for. It requires special technique and tools to make.

DURABILITY, WELDING & LASER CUTOUT

The Airblade is made in industrial aluminum with 1.5mm thickness, so it’s light weight, but strong and solid. There are 7 bents plus 10 welding points on each side to make the whole piece sturdy.

SAND BLASTING AND FINISHING

In order to make sure the finishing is durable, before anodizing and powder coating, the Airblade were sent for sand blasting. The sand blasting process will help to keep the color last longer and sturdy. Durability Tests were conducted for the powder coating, to make sure Compressive Tuning recieved the quality they asked for for the Airblade.
