Using a standard 2.7 diesel Nissan Mistral stock air filter, the next step is to fabricate a clamp using a 3.2 TIG wire. The air filter has a 70mm OD outlet hole that connects directly to the engine. Since this air filter is designed for single use and does not require washing or oiling, it simply needs to be replaced with a new one when necessary.
