Overview
A Honda Ridgeline owner gets a cold air intake built around a high-flow tube, a custom heat shield and an oversized washable cotton filter. The kit takes the place of the stock airbox and is made in the USA.
The reason to buy is airflow plus a filter you wash rather than replace, with the factory warranty left intact. The limit is scope: the kit fits one truck, and the listing gives no measured horsepower figure.
Who it's for
A daily driver or tow rig in the listed model years that is getting an intake upgrade. Owners of other vehicles, or anyone who prefers a disposable paper filter, should look elsewhere.
Pros and cons
- Washable cotton filter
- Replaces the restrictive OEM air box
- Custom heat shield part of the design
- Lifetime limited warranty
- Fits one truck only
- Actual horsepower gain not stated
Performance notes
A smooth intake tube and an oversized filter reduce restriction compared with the original housing, and the heat shield limits warm engine air reaching the filter. The maker says the design was dyno tested, though no gain figure is given.
