[TESTED] LIQUI-MOLY vs PENRITE Diesel Intake Cleaners - WHICH ONE IS BEST?? 

Germany vs Australia! Big vs Small! Liquid vs Foam! Sauerkraut vs Pie with sauce! Whichever way you look at it, this shoot-out promises to be very interesting!
In this video we pit Liqui-Moly Diesel Intake Decarb against Penrite P26 Diesel Foaming Intake Cleaner in a manifold cleaner shoot-out to see which one comes out on top! They each have to show their true colours through a range of off-vehicle tests. And by the end we have one clear winner!
EDIT: At 2:55 a viewer thought I said it was necessary to remove the whole inlet manifold in order to use these products. That isn't the case - I was summarising the instructions of each product which were slightly different, but both are just saying you need to remove something from the intake system so you can spray this product into the inlet manifold. In my case I removed the air intake hose directly before the manifold which was the simplest way to do this.
