Removing the IACV from the throttlebody for cleaning used to be a real pain because it is held in place from the factory with tamper proof bolts. Use this standard hex head bolt kit to replace the tamper proof bolts found on your OEM IACV valve and IAC motor. Having these bolts in place will make it very easy anytime you need to disassemble the IACV for cleaning. Just another small idea we came up with, we're always trying to make things easier for our customers.
