Manufacturer: Gates
UPC: 072053056167

This Gates radiator hose is used for increased clearance with cold air intakes and RBC/RRC intake manifolds on the 02-06 Acura RSX (DC5), 02-05 Civic Si (EP3), and 01-05 Civic (EM2) with k-series swap.

Advanced Fiber Construction. Exceptional durability and resistance to pressure extremes.

Premium EPDM Rubber Compound. Protects against the high temperatures of full throttle driving. Prolongs the effectiveness of coolant because it's 10 to 15 times more resistant to water permeation than silicone hose.

Does not touch intake tube. Problem solved. Easy install works great, good quality
Works Perfect

The hose works exactly how it should. Gives plenty of room for my intake and probably helps keep IATs down drastically.
Gates Radiator Hose

I have a injen CAI with K20z1 swap into a ep3 this worked greak to give my intake some room and looked great also
Inexpensive fix for cai/hose contact.
Josh | July 2nd, 2012
I bought this gate hose because the stock hose would lay on the rubber elbow of my injen cai and melt it. With gates hose installed i have no more issues like that. Easy to install and only 16 bucks.
