We are the original creator and designer of this aftermarket flex connector. This product was developed from the ground up by Daddy Does It, LLC (DDI™) and required more than five months of design, prototyping, testing, and refinement before the first connector was offered for sale.
Since its introduction, competing versions and overseas copies have appeared on the market. We didn't copy the aftermarket connector — we created it.
When you purchase from DDI™, you're buying directly from the company that developed the original aftermarket solution.
Created to meet the needs of Nissan owners running the 2.4L platform. This part is compatible with both KA24E and KA24DE engines.
Direct-fit air box connector for Nissan KA24E/KA24DE engines — replaces the cracked or deteriorated factory joint between the air cleaner and intake tube.
DDI™ Quality Assurance
Every DDI™ flex connector is individually inspected prior to shipment. As part of our manufacturing and quality assurance process, some connectors may receive internal flexible reinforcement in selected areas to ensure an airtight seal and maximize long-term durability. This reinforcement is fully compatible with the connector material and does not affect fit, flexibility, appearance, or performance.

This part matches OEM sizing and installs as a secure friction fit—no bands or clamps needed.
Because this part is designed to create a secure, sealed connection without clamps, it is manufactured using flexible TPU and optimized for durability and consistent sealing performance under engine vibration and heat.
Flexible TPU allows the part to conform slightly during installation, improving the seal and reducing the risk of cracking or air leaks compared to rigid or aged OEM components.
Original Nissan connectors still available on eBay are typically 20+ years old, brittle, and priced between $50–$120 used.
This part is brand new, flexible, and built for durability.
