Filter service - A lter service kit is available from LPE for cleaning and re-oiling the air lter (part
number SB-88-0005). The correct amount of oil for this lter element is 39 grams (1.4 ounces) of oil.
Replacement lters are also available from LPE (lter part number L660070105). How frequently you
should clean your lter will depend on your driving conditions. LPE recommends checking your lter
at every oil change or 3,000 miles. If there is a build up of dirt as thick as the wire mesh, then LPE
recommends you clean your lter. As dirt builds up on your lter, the restriction of the airow also
increases.
Many other items are available from LPE for your ZR1 Corvette including low temperature
thermostats, camshafts, ported throttle bodies and much more. Contact LPE, visit our web site, or
contact your LPE distributor for information about our other products.
For additional product installation information and technical support, contact LPE or your LPE
products distributor. You can also nd technical support and usage discussions regarding this product
and many other LPE products in our Internet forums:
