Maintaining a clean filter is a key element in getting the most out of your filter. Spectre Performance 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 Spectre Performance 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 Accu-Charge Kit. Although the filter is capable of much longer service intervals, for best performance, Spectre Performance would recommend that you never exceed 25,000 miles of driving without servicing the filter.
All of the plenums and airboxes are designed to fit a standard carburetor. 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 airboxes will fit. If you are already using a Spectre filter without an adapter it will fit. Also if your neck is 2-5/8 inches or 3-1/16 inches you can use P/N 4950 carb adapters to allow use of the plenums or airboxes.
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.
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. Then you just need to decide from the available options how to connect the air into your engine.
