S85 CSL Competition Carbon Intake System

Swipe right for info.

Massively enlarged.

The cross sectional area is nearly twice the stock intakes with a total 20% air volume increase over stock.

Enhanced Venturi effects.

The diameter differences between the upper intake tube and the side inlet accelerate airflow. The interior are further smoothened to enhance the effect.

Supreme carbon work.

Made from pre-preg carbon cured in autoclave, Infinity uses 2x2 weave pattern. The kit is available in gloss, or matte finish.

MAF-less.

This kit requires new Intake Air Temperature sensors and its relocation to the bumper's ducts.

Stage Tuning

Tuning is often offered in "stages" that optimize for your peripheral performance upgrades.

Here's how Sal defines his stages. 

Stage 1:

Standard cars. I highly recommend the sealed air intakes

Stage 2:

Optimized for primary cat deletes & aftermarket long tube headers.

Stage 3:

Optimized for V3 long-tube, equal length headers.

Extra specifications available: 

  • Raised RPM limit to 8500rpm
  • Idle RPM adjustments
  • VMax Limit removal
  • Cold start delete
  • Power calibrations with changes made to ignition, fuel, torque and VANOS maps

FAQ

Yes.

No! However, Sal and I are looking to see if a tune can be optimized for the larger air volume. TBD.

I first want to test these before making them available.

Yes! I used Turner's kit here. You'll need 2x.

Build journal: a special series
Reimagining the original BMW CSL prototype.

The CSL Plenum OE+ variant introduced in 2022, yet a few of us wanted more.

We wanted as close to the CSL prototype.

The Competition Spec aims at achieving this objective with a massively enlarged, fully sealed, complete carbon intake system running exclusively on AlphaN.

I've built upon the original Special Series to dive into the development, test fitment, performance testing and impressions of the Competition variant.

Enjoy,

Hear the OE+ variant

I expect the Competition Spec to be even louder.
Mandatory AlphaN mapping

The complete carbon intake runs using Alpha N as the engine mapping protocol.

The larger inlets will not have MAF bungs to optimize for space.

A new pair of Intake Air Temperature sensors will be required (like pictured).

Learn more about AlphaN
It's counterintuitive, but it works.

I documented in vast details the installation process of the OE+ plenum. I will further document the Competiton Spec specifics.

If your mechanic thinks he's smart and skips this, don't pay the bill.

Read my installation notes

Overall the car feels more responsive, pulls like a train! The sound is very S54 CSL-esque: addicting, intoxicating - all apply.

Sal @ InfinityDesign
Legacy knowledge.

InfinityDesign's unique product design and engineering is crafted by the grand-daddy of the most popular S85 products and tuners to hundreds of S85s: Salman.

As a former Evolve co-owner, he headed engineering & development for all products.

He notably signed off on numerous popular V10 products: e-tronic exhaust systems, headers, cat deletes, carbon intakes along with the V8 supercharger kits & tuning maps during the 2000s until he exited the company in 2015.
