The S85 V10 is notoriously sensitive : it loves cold air. They will easily suffer from heat soak with exposed filter designs.
The OEM sealed configuration is critical to these engines performance, yet it left a lot on the table.
In this Special Series, I document BMW M's sealed intake history, take a dive into the technical features of this unique aftermarket design, share my installation notes, talk tuning and record some clips with Luigi.
Enjoy,

14whp up top without a tune? Not bad - but I dislike dynos.
They're not the truth.
I believe power needs to be felt and measured on the tarmac. Most precisely, the 100-200 kph test.
Been there, done that.

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.
