SPOON SPORTS now offers the S-Tai Bonnet for the 11th Generation CIVIC TYPE R (FL5). This item is a must to keep the water and oil temperature in check for track driving.
Before pushing your car hard, securing enough cooling performance is essential. Increasing the capacity of your radiator is a standard step in the right direction, but it’s often not enough. That is why we decided to develop this product.
The front bumper of the FL5 has sufficient fresh air intake capacity but the problem was efficiently venting the hot air out from the engine bay. The large air duct design of our new bonnet triples the amount of airflow out of the engine bay, greatly increasing the cooling efficiency necessary for demanding track driving conditions. The air ducts on both sides not only facilitate the exit of heated air, but also effectively relieve air pressure from the wheelhouse. This helps to enhance downforce during high-speed driving to improve overall stability. The bonnet is constructed from lightweight, durable FRP material. When running our demo car continuously on track, overheating had always been an issue. While developing our radiators and thermostats, we came to realize that improving the efficiency of hot air extraction from the engine bay was a must.
That is how we started our development of the newly designed bonnet. We tested the new bonnet on our S-Tai racing car and confirmed the significantly improved cooling performance, with zero overheating issues during the hot summer season races in conditions over 35℃ (95°F). Many FL5 owners running their cars on track often install oil coolers to keep their oil temperature down. Our new S-Tai bonnet combined with an increased capacity radiator will enhance the oil temperature cooling performance, minimizing the risk of decreased oil pressure, thus ensuring stable, continuous performance.
