CARBON FIBER INJECTION STACK FILTER

 

If maximum airflow is what you are looking for, this airbox is your ticket, flowing at up to 2700 CFM. K&N has constructed the base portion of this assembly from carbon fiber to fit from 2"to 2-5/8" Hilborn, Kinsler and Engler stacks. This allows you to do away with clamping a filter on to each individual ram tube. Once the base has been put in place, simply slip the main filter assembly over the stacks. Easily done and at only 3.4 lbs., this airbox will allow your vehicle’s engine to breathe all the clean air it needs to make you a winner. As with all K&N filters, this is a washable and reusable air filter. Simply use our K&N oil and cleaner to service your filter.
