If your Jeep Wrangler JK feels a bit sluggish off the line, a cold air intake is one of the easiest wins you can make. This Rough Country Cold Air Intake for the 3.8L JK (2007–2011 models) relocates the air filter away from the warm engine bay, pulling in cooler, denser air that gives your combustion chamber more oxygen to work with — the result is a noticeable improvement in throttle response and a modest bump in horsepower.
- Designed specifically for 2007–2011 Jeep Wrangler JK with the 3.8L petrol engine
- Large diameter intake tube improves airflow significantly over the factory airbox setup
- Includes a premium reusable air filter — clean it and keep going, no replacements needed
- Straightforward bolt-on installation, no specialist tools required
- Backed by Rough Country's Limited Lifetime Warranty
- Note: this is the 3.8L version only — does not fit 2012–2018 JK models or diesel engines
As New Zealand's official Rough Country importer, Magwarehouse stocks this and a huge range of JK accessories. Give us a call on 09 250 1803 or swing by our Manukau workshop — no appointment needed.
