CSL Airbox

BUILD JOURNAL: SPECIAL SERIES
Buying the airbox is only half the way there.

These CSL airboxes are complex - the engineering & design expertise is not only for performance, sound but most importantly: reliability.

In this Special Series, I document my CSL airbox experience.

I take you into my unboxing of the Haimus Racing CSL airbox, the hardware checklist, the tuning dilemma, installation notes and my driving impressions with proper sound clips.

Cheers,

It sounds like the original.

Pre-preg carbon is used for its superior tensile strength and the ability to create a thin walled construction to uncork the CSL signature induction noise.

It flows better.

Flow optimized trumpets create more midrange power then any OEM CSL replica airbox from 3000 to 7500 rpm.

It stays cool for longer.

The IAT Sensor bung is placed closer to the front of the airbox compared to the OE design. This has been proven to avoid heat soak issues.

It's assembled to be reliable.

All fittings are physically locked into the carbon housings with a thread and custom nut. Haimus backs it up with a 5 years structural warranty

A simplified snorkel is optional.

A simplified, no flap design made from 3D printed ABS plastic: it's inexpensive and effective.
