Review: Perfect for a custom job - I purchased a K&N FIPK for my AP2 Honda S2000, but decided that I did not want to use the provided K&N filter and stick with the OEM Honda filter. They did not have the 3.5 to 3" coupler/reducer at PepBoys so I ordered it from desertcart. It arrived in a very nice box and included two quality clamps. I cut about an inch from the Honda OEM filter's neck and used the coupler to attach it to the K&N intake tube. It is a quality product and it seems to hold up pretty well so far. I had to adjust the clamps once, after the engine bay was hot and have not had to tighten them since. If I need any more intake couplers/reducers I will not hesitate to purchase from Spectre. Review: 2012 Jeep JK - Used this on my 12 Jeep jk, I removed the factory air box tube... Works Great ## Features - For use with air intake systems or intercoolers - Kit includes coupler and 2 clamps - Adapts a 3.5 inch intake system to a 3 inch inlet - Lifetime warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003JIDTQW | | Best Sellers Rank | #311,930 in Automotive ( See Top 100 in Automotive ) #13 in Automotive Performance Emission Systems | | Brand | Spectre | | Customer Reviews | 4.5 4.5 out of 5 stars (376) | | Date First Available | September 9, 2011 | | Exterior | Machined | | Is Discontinued By Manufacturer | No | | Item Weight | 0.01 ounces | | Item model number | 9541 | | Manufacturer | Spectre | | Manufacturer Part Number | 9541 | | Model | 9541 | | OEM Part Number | 9541 | ## Images ![Spectre Performance 9541 Black 3.5"-3" Coupler/Reducer - Image 1](https://m.media-amazon.com/images/I/71qcnHRptgL.jpg) ## Questions & Answers **Q: is it the silicon material or the hard one???** A: It is silicone. It gets a little on the soft side but I have not had any problems with it. I use this for the air inlet on my turbo and it's holding up so far. **Q: how long is this? all the ones i find are only 3" long and I need at least 3.5 but 4 would be comfortable.** A: The Spectre 9541 is 3" long. **Q: Are the measurements for the inner (id) or outer (od) of each end?** A: ID **Q: How heat resistant is this material? I will be using it to connnect a parking heater to factory ductwork** A: I believe this is really for automotive airfilter use. The engine bay could really get hot so i think it can withstand a decent amount if heat. I had mine for years and it still looks good. Only question is how close to the heat source is it...if its not really direct i think it would be ok. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for a custom job *by R***R on June 19, 2013* I purchased a K&N FIPK for my AP2 Honda S2000, but decided that I did not want to use the provided K&N filter and stick with the OEM Honda filter.
