Performance You Can Measure:

  • Dyno-proven gains of up to 16 horsepower and 19 lb-ft of torque
  • Features patented MegaRam (MR) Technology for optimized air velocity
  • Maintains safe air/fuel ratios throughout the powerband—no tuning required
  • Cold air intake design draws cooler, denser air for improved combustion
  • Aggressive throttle tone that enhances the driving experience

Premium Engineering and Construction:

  • 6061-T6 aluminum tubing with mandrel bends for unrestricted airflow
  • Fully serviceable Injen SuperNano-Web dry air filter with increased surface area
  • Patented Air Fusion technology for superior air delivery
  • Available in multiple finish options for personalized aesthetics
  • Converts to short ram configuration for versatility

Complete Kit Includes:

  • Precision-engineered aluminum intake tubing

The order was shipped promptly, and everyone was is good working condition. I will order from here again!!

Placing an order went very smoothly. Thanks.

I ordered from Autoplicity because they had the lowest price for an exhaust i was looking for. I was kind of iffy at first but then i read all the great reviews. Very fast shipping and delivery! I will be coming back for my next auto needs. Thank you autoplicity for your great prices and customer service!

I am pleased with Autoplicity. There was a miscommunication on shipment, but after a phone call, everything was handled. Looking forward to my parts coming in. Thanks guys!

I purchased an Optima Red Top 75 battery from Autoplicity and they have some of the best prices available. The item was shipped right away and they knew the inventory that was available, not like others who said there may be a 2 to 3 week shipping time frame. So far the service has been great and I look forward to continued great service.

i received item very prompt and for a great price!

good price. like the discount shipping.

Fast and inexpensive. Thanks.
