4 Inch PCM of NC DIY Fenderwell TBSS Intake

4" PCM of NC DIY Fenderwell TBSS Intake with optional LS7 MAF

Want to get the most out of your Trailblazer SS? Try our original four inch fenderwell DIY intakes! They run the filter through the fenderwell into the brake duct area, picking up fresh cool air. The 4″ MAF kits will include a new 4″ MAF sensor and connector shell, those that reuse the stock MAF will not. We save you time and money putting everything together as a package. Tuning & electric fans required, not optional. A MAF sensor adapter harness is offered for 4″ MAF kits, but not required. These intakes make 15+ RWHP over the competition!! Expect 20rwhp and 1-2 psi of boost on Magnacharged applications with our TVS 1900/2300 intake. Will not work on 112/122 series superchargers. Requires washer tank to be relocated (we offer a kit in the options). Optional filter socks available for those concerned about dirt/water ingestion.

• Intake Tubes *
• K&N Air Filter
• Silcone Elbows/Couplings & Straps
• Optional: Washer Tank Kit
• Optional: Filter Sock
• Optional: LS7 MAF

* There are two sizes available for the intake tube. Factory style intake connection or Magnuson TVS1900 and TVS2300 connection.
