In a scoop for 4WD Mechanix
Magazine, Dan Hiney installed the new MSD Atomic EFI on his Jeep YJ Wrangler 4.2L inline six
engine. This was a first for the 4.2L application and set the stage for exclusive testing. The test results are
impressive, as Dan describes in this HD video footage. Our interview and driving action took
place live at the Rubicon Trail during the 2012 Wheelers for the Wounded Super Rubicon Event.
As co-organizer for the WFTW, Dan's Jeep must perform
flawlessly and dependably. It also resides at California, where emission requirements dictate a clean tailpipe.
Not only did Dan Hiney's 1989 Jeep YJ Wrangler meet every trail requirement, it has tested with lower
tailpipe emissions* than the requirements for this Jeep!
of summer 2012, the new MSD Atomic EFI does not carry a California E.O. number for the Jeep 4.2L
inline sixes. We're encouraging MSD to pursue a California E.O. number for this Jeep application and will
update. Although Dan's Jeep meets/exceeds the standards for this vehicle, an E.O. number is necessary
for California emissions compliance.
