I do have a plastic cap that came with the wideband I could put on the end oft he narrowband to help protect it from the elements, but it might melt to the tip. How do I know this? I had an o2 simulator installed on the Evo and proceeded to wrap the end with electrical tape thinking I would protect it. 10k miles later I reverted the exhaust back to stock and had to literally scrape the bubbled up tape off the tip in order to reuse the narrowband. Lesson learned... the tips of o2 sensors get hot!
