Set up in 1995, Tonglu Valves Manufactring Co.,Ltd. is one of the leading China flexible pipe manufacturer and supplier in Yongjia County of Zhejiang Province. We manufacture all products strictly conforming to the API, JIS, ANSI, BS, GB, NF and DIN standards. Our oem flexible pipes are available to users on request and are used for municipal works, petroleum, chemical industry, power station, metallurgy, national defense, and scientific research fields.

PVC pipe is great stuff for making intake snorkels but, in this case, it would have been very difficult to route a large enough pipe from the fog light area to the airbox. The problem is the limited selection of angles available in PVC bends.
An easier option is flexible pipe. But note that not all flexible pipe is the same - many have a near-smooth inside wall (which helps maintain airflow) while others are very convoluted (which restricts air flow). Cost also varies massively so shop around. Our 3 inch flexible pipe had been sitting in the shed for several years so it cost nothing.
With the original intake snorkel removed, we could fit the end of our flexible pipe to the airbox. This was easy in the case of the VR4 – our flexible pipe slipped tightly over the snout of the airbox.In some vehicles you might be able to run the flexible pipe from the airbox to the front of the car without cutting any metal. However, in the VR4 we were forced to put a hole through a difficult to access section of the inner guard alongside the battery tray. Note that there’s plenty of support structure in this vicinity, so you can get away with creating a 3 inch hole.

Mesa's flexible pipe is designed for Aboveground Storage tank applications such as roof drains and skimmer lines. Mesa's flexible pipe designs are compatible for continuous service, both externally and internally, in a wide range of pH solutions and chemicals.
