The Delta Force "U-fit" air intake kit is perfect for the person doing an engine transplant in a "classic car" or race vehicle and needs a solution for fabricating a custom air intake. This universal system comes complete with a custom molded Cross-Linked Polyethylene (XLPE) high-flow 4.00" intake tube with numerous pre-set cut guides and various bend angles for versatility and adaptation under the hood. Also includes a large diameter high-flow 8 layer cotton gauze air filter, which traps more dirt than typical 6 layer designs and comes pre-oiled and ready to run. The filter is reusable and should provide a lifetime of service when maintained properly with our Delta Force Refresh kit. Other features include a blade style MAF sensor adapter, various sizes of high quality reinforced silicone couplers, stainless steel clamps, universal brackets and hardware to help fabricate a complete air intake system. Note: Some tuning may be required. This intake system is intended for use on pre-emissions vehicles, or non-street legal competition race vehicles only.
