When it comes to your Jeep Wrangler's engine, the colder the air it ingests, the more horsepower it produces. Unlike warm air, cold air is so much denser. It carries more oxygen per volume, which translates to a more efficient burn and more power generated during combustion. This is the reason vehicles are outfitted with a cold air intake. With this component installed, your Wrangler will perform better even in cold weather. So if you want a significant improvement in your ride's performance and fuel economy, outfit it with a Jeep Wrangler cold air intake. Just make sure you won't use your Wrangler in going through high waters because water ingestion can damage the engine.
