What to Look For Before Buying

Choosing the right intake requires understanding your vehicle and performance goals. You must consider if you need a full kit or just a pipe. Always verify compatibility with your engine before buying.

Check Verify Vehicle Compatibility

Check your engine year and model before ordering. Diesel intakes are specific to engine types. A minor year difference can prevent a proper fit.

Value Choose Your Filter Type

Select between dry and oiled filters carefully. Dry filters are convenient and need no oiling. Oiled filters provide filtration but require more maintenance service.

Rating Evaluate Construction Materials

Look for high-quality aluminum or heat-resistant plastic housings. These materials prevent heat soak and ensure durability. Avoid cheap plastics that may warp under high heat.

Verify Check Legal Requirements

Ensure your intake is CARB-compliant if you live in a regulated state. Many performance intakes are for off-road use only. Check for EO numbers before buying.

Frequently Asked Questions

Does a new intake increase fuel economy?

While improved airflow helps, fuel economy gains are often minimal. Most owners notice better throttle response instead. Results vary by driving style and tuning.

Can I install an intake by myself?

Most kits are bolt-on and use basic tools. Some might require mechanical experience. Always read the instructions or watch a video before you start.

How often should I clean my intake filter?

Cleaning depends on your driving environment. Dusty areas require frequent cleaning to maintain airflow. I would check your filter every 10,000 miles.

Will an open intake hurt my engine?

A quality intake will not hurt your engine. Just ensure the filter is seated correctly to prevent dirt from entering. Maintenance keeps the engine healthy.

Are these intakes compatible with tuned engines?

Yes, many systems support the air requirements of tuned engines. High-flow intakes help engines reach their potential after tuning. Consult your tuner for advice.
