This gloss-black Wehrli Stage 2 intake kit fits 2011–2016 Chevrolet 6.6L Duramax LML applications and replaces restrictive factory parts with a fabricated aluminum intake pipe, air box and dry filter to improve airflow, turbo spool and intake temperatures. The kit includes a 4.8-inch cast intake horn, silicone boots, stainless t-bolt clamps, removable air box lid with pre-filter cover, and installs bolt-on; 2011 trucks need a PCV valve update for compatibility.
