Stinger® System

(2001-08) CLASS-A MOTORHOME, W-Series and P-Series: Affordable stainless-steel Stinger includes Banks' all-new Ram-Air intake system (available for W-Series only) that eliminates restrictions for effortless flow. Optional AutoMind Programmer removes the factory-imposed power delay so you'll have acceleration when you need it. Stinger delivers top gains of +51 hp and +68 lb-ft torque to the rear-wheels, plus better fuel economy. Because engine airflow is the central principle to Stinger and all Banks power-enhancement products, you'll have a more durable vehicle and longer engine life.

Includes: High-flow Banks Ram-Air intake system (W-Series only) with Ram-Air filter & service kit, filter housing cover, large-sized tubing, and adapter; AutoMind Programmer (available for '01-05 models); Stainless, constant-diameter Monster exhaust with 4" tailpipe; Polished-stainless, 5" double-wall tailpipe tip with rolled edge; Comprehensive Owner's Installation Manual.

8.1L motorhome Stinger & OttoMind: Totally pleased

2010-08-20

Thank you for a great product. I installed the Stinger System and OttoMind Programmer in a 2005 Allegro Bay, 38', 23000 lbs. This system has given me power on demand and increased fuel economy by a mile per gallon. I am totally pleased.
