Description
Product Description
A combination of heat, oil, and boost pressure at the turbo outlet expose the general weakness of the stock turbo outlet pipe, resulting in degradation of the stock hose wall and metal couplings. After suffering this hose failure (and the associated boost/power loss) customers are then faced with an expensive replacement, however poor quality, from BMW.
The Forge Motorsport solution is a 4ply fluoro-lined silicone hose designed to withstand the typical temperature, pressure, and oil corrosion at the turbo outlet juncture. CNC machined alloy couplers achieve a snug fit to complete another high quality Forge Motorsport product.



Please note this kit is not supplied with the male coupler o-ring, and the original o-ring must be removed from the stock male coupler for fitment to the Forge Motorsport male coupler. If the o-ring needs to be replaced an original can be bought from BMW under part number 11618506786, or 11617791470. These two part number represent the original and superseded o-ring part number, both of which are same quality and size o-ring.
Please note: It is very important to fit this hose following the process described in the fitting guide. Failure to do so will result in the hose appearing too short for purpose. The original o-rings/seals must be retained.

Warranty
10 Year Warranty Information
The majority of Forge Motorsport products come with a limited 10 Year Warranty (brakes pads excluded). All warranty claims must be accompanied by the original proof of purchase to enable us to help you. Failure to supply this proof will result in your claim or enquiry being denied.
For further information, please call our customer service team on +49(0)3222/1097-308 or email info@forgemotorsport.eu.
Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator, or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
This warranty does not apply to any defect in the goods arising from fair wear and tear, wilful damage, accident, negligence by you or any third party, use otherwise than as recommended by the supplier, failure to follow the supplier’s instructions, or any alteration or repair carried out without the supplier’s approval.
