Harrop Cold Air Intakes: Maximum Airflow for Your LS Engine

Harrop Engineering is best known for their supercharger kits, but their cold air intake (CAI) systems deserve attention in their own right. Designed to complement both naturally aspirated and supercharged LS applications, Harrop's intake systems are engineered for maximum airflow and thermal efficiency - and they're available from BYE Performance in Perth.

Why Upgrade to a Harrop Cold Air Intake?

The factory airbox on most LS-powered vehicles is a compromise - designed to minimise noise, pass emissions requirements, and fit within tight packaging constraints. Performance is a secondary consideration. A Harrop cold air intake is engineered with a single priority: maximum clean, cool air delivery to the throttle body.

Cooler air is denser air, which means more oxygen molecules per unit volume. More oxygen means the ability to burn more fuel efficiently, which translates to more power. The separation between the filter and the engine bay heat sources is a critical feature of cold air intake design.

Harrop's Engineering Approach to Intakes

Harrop doesn't develop standalone products in isolation - their intake systems are engineered as part of the complete induction system picture. This is especially relevant on supercharged LS applications, where the intake system leading into the supercharger is a meaningful constraint on airflow. Harrop's CAI systems are designed to complement their FDFI supercharger range, with matched throttle body sizing and airflow dynamics that don't create a restriction earlier in the system.

Integrated Throttle Body Options

Harrop offers high-flow integrated throttle bodies - including 110mm and 115mm options - designed to pair with their supercharger and intake range. On a supercharged LS application, the factory 90mm or 102mm throttle body can become a restriction at higher power levels. Upgrading to a Harrop integrated throttle body as part of an intake system upgrade removes this bottleneck.

Dyno-Proven Results

Harrop's engineering approach relies on dynamometer validation. Every product they develop is tested on their in-house dyno before release. This means the power gains quoted for Harrop products are based on real measurement, not marketing claims.

Which Applications Does Harrop Intake Cover?

Harrop's intake range primarily targets the LS engine family - LS1, LS2, LS3, LSA - in both supercharged and naturally aspirated configurations. Applications include Holden Commodore VE/VF (including HSV variants) and generic LS-powered builds. Consult with our team at BYE Performance to confirm fitment for your specific application.
