A hose kit developed in-house by do88 that replaces the car's original throttle body hose. These hoses are made exclusively from high-quality silicone for the best durability and finish. With three to five layers of reinforcement, depending on the inner diameter of the hose, they withstand high pressures and temperatures over a long period. The original is made of rubber, which not infrequently cracks as it dries out. This is the solution to that, and it also improves the appearance considerably. There is no performance difference between the colours. Matching hose clamp packs are available, designated do88-kitxxx. Check that the number of the kit matches the number of the hose clamp pack. All original part numbers are given as reference numbers only.
