I recently purchased an anti-smog hose for my automotive braking system and was pleasantly surprised by the Dayco 80371 .Based on our own experience this hose exceeded our expectations with its easy installation process and improved performance. The quality of construction is top-notch and the hose appears durable enough to withstand the test of time. The downside is that it is slightly costly when compared to others in the market. Overall, this is a brilliant product that is worth purchasing for anyone looking to upgrade their vehicle's performance..
