Investment boosts market penetration of innovative pulse plug.

For Immediate Release

ALBUQUERQUE, N.M./EWORLDWIRE/April 14, 2008 --- Robeco Clean Tech Private Equity II along with SAIL Venture Partners L.P. has invested $5 million in Enerpulse Incorporated, the developers of the fuel-efficient Pulstar pulse plug. This additional funding brings the Enerpulse "B" round to a close at $10.5 million, in which SAIL and Altira Group provided initial funding. The funds will be used to accelerate and globalize sales of Pulstar, the first real breakthrough spark plug technology in over 120 years.

Pulstar is a unique type of spark plug called a pulse plug. Unlike spark plugs, pulse plugs have an integrated electrical circuit called a capacitor that boosts energy to the spark much like a camera flash boosts light. The resulting more robust spark improves engine combustion yielding better fuel economy and engine performance.

"The investment made by Robeco and SAIL goes way beyond a simple financial need," said Daniel Parker, chief executive officer of Enerpulse, Inc. "Both have great reputations, and Robeco's presence in Europe is a strategic link to our globalization plans."

Pulstar was launched into the $12 billion automotive aftermarket in June of 2007 after four years of development. Spurred on by rising gasoline prices and concerns over global warming, consumers have responded emphatically to the product, driving compounded monthly sales growth of 33 percent. In tests conducted at Enerpulse, Pulstar on average improves fuel economy by 6 percent across all vehicles tested. Even fuel-efficient hybrid vehicles have experienced significant improvements.

Keimpe Keuning, senior investment manager at Robeco, commented that, "Our interest in Pulstar was peaked by its simplicity as a drop-in replacement for spark plugs with potential - similar to the energy-saving light bulb. It is a great solution to soaring fuel prices that have topped $8 a gallon in Europe. In North America, 400 million spark plugs are sold each year to keep the 250 million existing cars running. These are compelling opportunities for a product that has already seen stunning customer acceptance."

Thomas Cain, founder and managing partner of SAIL, commented that, "Our studies show that using the Enerpulse replacement plug will save more oil globally, than all ethanol plants in current production and under construction."
