Review on Four Seasons 38904 Orifice Tube: 🚗 Optimal Performance for Your Automotive Cooling System by Rick Gondoras

First of all, this is NOT a panacea for a poor network system. But here in South Florida, she does what I want. In heavy traffic, long idle, at temperatures above 90 degrees, cooling improves, blowing 44 degrees on a 95 degree day. A solid OE pipe will creep up to 60 under the same conditions. On the highway it's about the same as any solid pipe, I get 42 to 47 vent temps depending on the ambient temp. idle. The typical customer, even a warned one, will complain. But for my own car, I will live with noise to improve the heavy traffic.
