The best HPS parts in this collection are its high-temperature reinforced silicone radiator hose kits, listed for the 2009-2013 Nissan GT-R and the 2006-2014 Mazda Miata 2.0L in black, red, and blue, plus an HPS Performance shortram air intake kit with heat shield for the 2012-2017 Subaru Legacy 2.5L non-turbo. If your factory rubber coolant hoses are ageing, start with the hose kit that matches your exact car and years, then pick the colour.
Radiator hoses carry hot coolant between the engine and radiator every heat cycle, so they live under heat, pressure, and vibration. A reinforced silicone hose kit is the common replacement when original rubber hoses soften, swell, or crack, and the listings here describe the kits as high-temperature reinforced silicone and as OEM replacements, meaning they are shaped to replace the factory coolant hoses on the named application. Colour is the other choice in this range, with black for a factory look and red or blue for a dressed engine bay. An intake kit works differently: the shortram intake for the Legacy replaces the factory intake tract and includes a heat shield, which helps separate the intake from engine-bay heat.
HPS is the single brand in this collection, and its range here splits cleanly into cooling and intake. On the cooling side, the silicone radiator hose kits cover two very different cars, the 09-13 GT-R and the 06-14 Miata 2.0L, each in the same three colours, for owners replacing every coolant hose at once during a radiator service or engine-bay refresh. On the intake side, the Performance shortram kit for the 2012-2017 Legacy 2.5L non-turbo, in black and including a heat shield, is a bolt-on intake option for a car with fewer performance parts than the turbo Subarus. Through these products, HPS serves the maintenance-plus-upgrade buyer: factory-fit hoses with a colour choice, and a simple intake for a naturally aspirated application.
Start with the HPS silicone radiator hose kit in black for the 09-13 GT-R, also listed in red and blue, or the HPS shortram intake kit for the 2012-2017 Legacy 2.5L. For the wider cooling job, browse Cooling, Performance Radiators, and the Nissan GT-R collection, and read our explainer on the differences between intake systems before choosing an intake style.
Are silicone hoses a direct OEM replacement?
The kits here are described as OEM replacements for the named applications, the 09-13 GT-R and the 06-14 Miata 2.0L. Confirm your exact year and engine before ordering, and plan on fresh coolant and a full bleed after any hose change.
Does the Legacy shortram intake need a tune?
Intake changes can affect airflow readings, and requirements vary by car. This kit is listed for the 2012-2017 Legacy 2.5L non-turbo and includes a heat shield; check tuning guidance for your car before assuming no tune is needed.
How hard is a radiator hose kit install?
It is a drain, swap, refill, and bleed job with basic tools, done on a fully cooled engine. Many owners pair it with a radiator service while the system is drained.
Does hose colour change performance?
No. Black, red, and blue kits in this range are the same application in different finishes. Choose on look, and match the kit to your year and model instead.
