Filter service - A filter service kit is available from LPE for cleaning and re-oiling the air filter (part
number SB-88-0005). The correct amount of oil for this filter element is 35 grams (1.23 ounces) of oil.
Replacement filters are also available from LPE (filter part number L660050704). How frequently you
should clean your filter will depend on your driving conditions. LPE recommends checking your filter
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 filter. As dirt builds up on your filter, the restriction of the airflow also
increases.
Many other items are available from LPE for your Cadillac CTS-V including low temperature
thermostats, camshafts, ported throttle bodies, port matched intake manifolds, intake manifolds, CNC
ported cylinder heads, supercharger kits, short throw shifters, complete engine packages and much
more. Contact LPE, visit our web site, or contact your LPE distributor for information about our other
products.
Performance note: The Cadillac CTS-V is sensitive to intake air temperature (IAT) and engine coolant
temperature (ECT). Small changes in IAT and ECT can cause the vehicle to have less ignition timing
that can result in reduced power output. In addition, the CTS-V has a fairly sensitive knock sensor
calibration and may be reducing the ignition timing due to knock sensor activity. When running at
the track, be sure to keep the water temperature at or below the thermostat temperature for optimal
performance. When testing your vehicle on a chassis dynamometer, make sure all testing is done at
the exact same IAT and ECT in order to insure accurate testing. You will also want to monitor the
powertrain control module (PCM) to make sure that the tests are all performed at the same ignition
timing and that knock retard is not active during the test. If you don’t have a GM Tech 2 diagnostic tool
to check and record engine operating parameters, other diagnostic tools exist including the DashDAQ
and software that will run on your laptop computer such as AutoTap and EFILive.
