M&B Enterprises had a seminar about and would install the aero products. Some installs were made. He indicated as a diesel engine expert that this is the BEST way to get spent gases out on the engine. The air filter and the muffler set up is most important for the engine to do its best, and good quality fuel. Of course he had an additive by "Power Up". He indicated never store your coach without the additive and a full tank. This guy did a great install from the ones I saw. Do not know his schedule or location. 520-471-3535 or email: wmajbon@yahoo.com
