Use heavy duty Caps in ECU/ECMs

It becomes well known to people that rebuild ECU/ECMs caps fail all the time. When the caps fail they deposit an acid (like battery acid) all over. If the ECU/ECMs are left for months they can destroy the circuit board. WHAT caps are the ones to use?

Here's what I ordered from digikey.com. Rated for 1000hrs @ 105 C temperature.
The high temp rating is what to look for - heat kills electronics
