Halltech Stinger™-689 cfm Super Flow Filter


Availability:: Ships same day
Product Code: ST689

As indicated in the nomenclature, the Halltech 689 cfm filter is our proprietary high flow filter just released for the C7 StingerCKN and C7 Stinger-Hybrid intake systems.  It also fits the Halltech Yellow Jacket as a replacement filter.  Lingenfelter Engineering, Katech Performance, and K&N Engineering tested our filter several months ago vs. our standard filter and a full synthetic version of the filter.  The results on the flow bench: Halltech's Stinger-689 cfm @ 1.5" H2O.  The base filter now used on all StingerCKN and Stinger-Hybrids- 587.5 cfm.  The synthetic version-399 cfm.  We will be discontinuing the 587 cfm filter beginning with orders received in June.In stock.  If your C7 is stock except for our StingerCKN or Hybrid intake, you will not need this upgrade for better performance  We are seeing an average 14 RWHP/15lb-ft torque.  If, however, you plan on mods such as headers, cam, etc. this filter will flow to 800 HP with no problem or restriction to flow.  This was the filter Halltech tested at a 1/4 mile off road track and recorded 11.3 sec from 0-120 mph with our C7 Auto, with minor tuning and our Hybrid Stinger.  For comparison stock filter flows 224cfm@1.5" H2O, and aFe's Momentum intake at 318 cfm @ 1.5" H2O.  The Halltech ST-689 flows 216% more than the aFe based on their claim and 308% more than stock.
