Fitment Notes01-05 Honda Civic with K-Series swap and RSX/02-05 Civic Si Radiator
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.
Electro-chemically Resistant ECR Tube Stock. Combats the leading cause of premature hose failure - electrochemical degradation (ECD).

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

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.
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.

Gates upper rad hose
Hose is perfect if u have a CAI as it routes coolant away. I have an AEM CAI, & stock hose sat right on CAI piping. Though I had to trim the hose where it hooked up to the head to keep it from resting on my battery, all & all, very satisfied with product.

Great product. I have an EP3 with the stock motor and an AEM V2 intake and my old hose would rub against it. With this hose it clears is just fine. Great for the price.

I have an ep3 with a k24a2 and an old aem cai. The upper hose was hitting the cai hard and raising my iat temps to pretty much my motor temp lol. I put this on and my iat is a steady 84-95. Thanks clubep3!

Great product for RBC
Bought this because I was tired of my radiator hose rubbin' my Injen intake coupler and raisin' the temps (at least a little, lol). Took a whole 2 minutes to swap out and it looks great. Watch out for coolant spillage though!

This radiator hose is a must for the rbc and cheap. So if your doing the rbc swap i highly recommend. Makes it so much easier and looks clean.

My CAI was rubbing the stock hose and I haven't even installed my RBC yet. Hose was easy to install and clears everything just fine. Recommended for anyone that owns an RSX.

Goes around the cold air intake hose just as advertised. Does not touch the intake. Great fitment also.

Gates Hose for k24 w/ RBC and CAI
I have a k24a2 swap in my DC5 with the RBC manifold and Injen CAI and this hose fits amazing for the application. Getting the stock hose off is a bit of a PIA but hose is worth it and needed.

it's cheap but high quality product. well i have a RBC intake manifold, and it fit perfect around my CAI piping. recommened to others that have a RBC IM and a CAI..

Very nice, How much?
Proof that inexpensive does not equal cheap, this fit around my club RSX injen CAI very nicely, routed it off the tube and is a high quality unit.
