The stock Explorer main intake is shown below. The outside diameter of the coils is about the same as the inside diameter of the Lightning intake. So I cut off the section of the Explorer tube that mates with the MAF sensor leaving two of the coils. Then I applied Shoe Goo between the two coils and inserted the section into the Lightning hose. After the 24 hour drying time I tightened the hose clamp to reinforce the joint, applied vinyl conditioner to the Explorer section and installed the assembly. Thankfully, no modification of the air filter enclosure is needed due to the slight curve in the Explorer section.
