Frequently Asked Questions (FAQs)

1. Do fan spacers work?

Yes, fan spacers can be effective in improving airflow and reducing noise emissions in suction-type applications. By using inlet spacers, fans can achieve higher flow rates and lower noise levels, resulting in better performance.

2. What are the negative effects of spacers?

Adding wheel spacers can have some negative effects. It can increase the tire scrub radius, which can alter the vehicle's handling and make slow-speed turning more difficult. Additionally, adding more components increases the potential for failure.

3. Does a fan shroud improve cooling?

Yes, a fan shroud can improve cooling by blocking out air that isn't drawn through the radiator. It creates a vacuum that allows the fan to pull air from the entire surface area of the radiator, enhancing the cooling efficiency. Additionally, a shroud can also protect the radiator from engine heat.

4. What is better, a clutch fan or flex fan?

For high rpm use, flex fans are considered an upgrade over clutch fans. They are particularly suitable for modified vehicles turning 6,000 to 8,000 rpm. Flex fans have the advantage of moving more air, resulting in better cooling performance.
