X 2 with 4.3LXJ
You might notice ....
a slight fuel consumption increase,
fan noise increase,
and a drop in engine power according to the butt-dyno.
Lots of faerie stories out there about huge fuel and HP variations .... but none seem to be supported with proper facts and figures pertaining to the XJ ..
Would be nice if someone did a - before and after, Dyno test on HP outputs .... hint hint ..
