Hi-Flow Air Filters for GM Diesels

  The stock paper air filter is quite restrictive and changing to a Hi-Flow Air Filter will allow the turbo to spool up easier and in most cases you will hear the turbo whirring as it pulls more air. To help the air flow better I also recommend removing the restriction in the fender, some call this part the "snorkel", even though it has nothing to do with water.  

Note:  I recommend removing the air box completely whenever replacing 6.5 turbo diesel air filters to make sure the box is clean and the filter is fitting correctly, this is especially important with other make filters. Click here for info and pictures on air box and "snorkel" removal.

 Allowing the engine to breathe better will add efficiency and performance and should help increase mpg, provided you maintain the same driving habits, but sometimes it's hard to resist using the added power. 

 Since 1978 I have used the K&N washable  air filters which are the oil impregnated cotton gauze (OICG) type.  We found that were good for performance applications, but over the last few years other companies have produced similar filters, we found one company who makes very high quality filters and we met with them to discuss our needs.  These filters IMHO they are much better quality, the deeper pleat design creates more surface air area which allow greater flow and as the filter gets dirty the flow and filtration stays good longer.  

 If you are considering any "FOAM" type filters. Click here to read the WARNING about foam air filters. 

 With many other filters it's all too common for the seal to deform allowing unfiltered air to pass by the filter. I find the seal on these to be much better quality and have not seen any indication of possible deformation.

 The photo above shows the our red filter (red) note the nice rectangular shape, straight sides then how this compares to the compared to the other (black), note the mis-shaped look of the seal.

 The photo above the wire mesh on the other filter is not properly covered by the seal material, note the more exacting shape of our filter.

  In our testing after installing our filters I noticed an immediate power gain and could hear and notice the turbo spool up faster.
