Genuine BMW Intercooler C-Clip - N54/N55 - E9X E82 E84 E89 - 17517798485
Genuine BMW # 17517798485, found on the inlet and outlet ports of some N54/N55 intercoolers
This part is listed by BMW as BMW part number 17517798485 (17 51 7 798 485) and is described as Genuine BMW Spring Clip, used on both the inlet and outlet side of the factory front mount intercooler (FMIC) found on many N54 & N55 powered BMWs, including E82 135i / 1M, E89 Z4 35i & 35is, E90 E92 E93 335i 335xi 335is & 335d, and E84 X1 28i, 28iX (4 cylinder N20), and 35iX (6 cylinder).
These pesky spring loaded C-clips are part of the quick-connect attachments on the factory intercooler. With age, time, heat, and exposure to the elements, the springs can become weaker than originally intended, which could allow the intercooler pipe to blow off, and leave your 135i, 335i or other "35i" power BMW on the side of the road. Likewise, if you have increased the boost on your BMW, the old original C-Clips on the FMIC might not cut it any more.
This Genuine BMW replacement is a good idea if you are either working around the intercooler OR if you are upgrading your intercooler to higher performance intercooler (such as our CSF or Wagner upgrades). Moore boost means a higher likelihood of blowing an intercooler hose off, so a fresh C clip on both ends can help avoid that.
Each C Clip is sold individually. Two clips are used per car / per intercooler, so be sure to order to if you are doing the job right.
