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.
