We have several in-house dynomometers that we use to measure power. It is important to know that dyno
numbers are relative, and should be used as a reference or as an indicator.
How often should I clean & re-oil my Spectre air filter?
Maintaining a clean filter is a key element in getting the most out of your filter. We recommend
that you inspect your filter during all of your manufacturers scheduled maintenances for your vehicle
or every 7,000 miles. Driving conditions play a key factor in maintaining a clean filter. If you live
in a dusty or harsh environment then we recommend that you service your filter more frequently. If
there are any portions of the screen that are not visible (covered by dust or dirt), then you need to
clean the filter with our Accu-Charge Kit. Although the filter is capable of much longer service
intervals, for best performance, we would recommend that you never exceed 25,000 miles of driving
without servicing the filter.
All of the plenums and air boxes are designed to fit standard carburetors. To determine if it will fit
yours you can measure the neck of the carburetor and if it measures 5-1/8 inches the plenums or air boxes
will fit. If you are already using a Spectre air cleaner without an adapter they will fit. Also, if your
carburetor neck measures 2-3/8 inches use adapter part number
4952 or if your carburetor neck is 3-1/16 inches use adapter
part number 4953.
Welded elbows allow the bend to be made in a smaller radius (tighter bends) which in small quarters can
be important. If you prefer mandrel bent elbows these are now available.
I have installed a custom intake and now my engine light comes on. What is the problem?
The MAF sensor was designed to detect the airflow as it passes through the original diameter inlet. Now
that you have a larger intake the MAF sensor is triggering the engine light. To resolve the problem you
may have to install a MAFS calibration kit (3 inch dia. P/N 9405 or 4 inch dia. P/N 9705) This allows you
to select an insert that is appropriate for your MAF sensor and will adjust the internal diameter to
prevent the engine light problem.
The modular nature of the program means you can design the system to fit practically any car. First you
need to decide the diameter tubing that is appropriate for your car. Large vehicles or large volume
engines require more air and a 4 inch dia. intake is appropriate. Smaller cars or vehicles with limited
room in the engine compartment may require a smaller intake. Next decide what method for routing the air
is appropriate, do you have room for an airbox? Is a plenum a better choice. Next decide where the air
is going to be coming from. Can you bring air from outside the engine compartment? Is there a place
under the hood that you can get cooler air? After you have an idea of the requirements for your system,
take a look at the available tubes and couplers on our website. Then you just need to decide from the
available options how to connect the air into your engine. Specific questions can be addressed by emailing
our Tech Department - Tech@SpectrePerformance.com.
We have recently revised several of our intake kits. If you need help with installation, or need
replacement parts, here’s how to identify whether you have a Version 1 kit or a Version 2 kit:
P/N 9908: Version 1 kits have have a straight coupler on the throttle body with a "J"
shaped tube. Version 2 kits have a 90° coupler on the throttle body and a straight tube.
P/N 9909: Version 1 kits have have a straight coupler on the throttle body with a 2-piece
intake tube. Version 2 kits have a 90° coupler on the throttle body and a single-piece intake tube.
P/N 9910: Version 1 kits have a 2-piece intake tube. Version 2 kits have a single-piece
intake tube.
P/N 9918: Version 1 kits have a 2-piece intake tube. Version 2 kits have a single-piece
intake tube.
P/N 9920: Version 1 kits have a 2-piece intake tube. Version 2 kits have a single-piece
intake tube.
P/N 9922: Version 1 kits have a bracket welded onto the tube and use a rubber vibration
mount. Version 2 kits do not have any brackets welded to the tube.
P/N 9925: Version 1 kits have a bracket welded onto the tube (near the MAFS mount) and
use a rubber vibration mount. Version 2 kits do not have any brackets welded to the tube.
P/N 9932: Version 1 kits have a bracket welded onto the tube and use a rubber vibration
mount. Version 2 kits do not have any brackets welded to the tube.
P/N 9935: Version 1 kits have a 2-piece intake tube and the filter is located behind the
bumper. Version 2 kits have a single piece intake tube with the filter located under the hood.
P/N 9960: Version 1 kits have a bracket welded onto the tube and use a rubber vibration
mount. Version 2 kits do not have any brackets welded to the tube.
P/N 9962: Version 1 kits use a filter with a 3" I.D. flange, attached directly to the
tube. Version 2 kits use a filter with a 6" I.D. flange attached to a velocity funnel.
In order for an intake to be considered for a C.A.R.B. exemption, it must have been submitted to the
California Air Resources Board for evaluation. It must be a complete kit, with everything needed to
install it included in the box. It must have provisions to connect all emission control devices so
that they function as they did with the factory intake. Lastly, it must be tested on a vehicle to
show that it doesn't alter the emission output of the vehicle.
Most of the vehicle-specific kits we offer currently have a C.A.R.B. exemption, or have been submitted
to C.A.R.B. for evaluation. The website shows which kits are exempt. Also, you can visit the California
Air Resources Board website showing our current intake kit exemptions.
If your vehicle has a custom intake that was created using our modular components, although it may run
great & increase performance, it will not be C.A.R.B. exempt even if you connect all emission control
devices. If you live in an area that requires a smog inspection, such an intake will fail the visual
inspection portion of the test. In order to pass, the stock intake must be reinstalled.
How do I get a replacement C.A.R.B. Exemption Decal?
If you have purchased an intake kit, for which we have a C.A.R.B. exemption (see previous FAQ), and
need a replacement decal, the following information will be required in order to comply with C.A.R.B.
regulations:
1) Name & mailing address
2) Vehicle - Year, Make, Model, and engine
3) A copy of the purchase receipt for the intake kit (or a picture of the kit installed on the vehicle)
4) A copy of the vehicle registration
Before we can send a replacement decal, we must verify that the kit was made by Spectre, that it is C.A.R.B.
exempt, and that it is on a vehicle for which the exemption applies. If you do not have the purchase receipt,
you can send us a picture of the intake kit installed on the vehicle. Please note that replacement C.A.R.B.
decals can only be sent to the vehicle owner at the address listed on the registration. If the address on
the registration isn't current, please include a copy of a utility bill (or similar document) that verifies
the current address of the vehicle owner. To get started go to our Replacement CARB
Decal Form.
This information can be sent via email to
Tech@SpectrePerformance.com or by U.S. Mail to our contact
address.
