Fast Toys High Flow Black 98 mm LS1 Air Lid
Powerful LS1 motors require higher airflow than the stock air lid and MAF can provide. Until now, you were stuck using a small MAF or a reduction coupler with a GM MAF. Both of these restrict airflow and cost you horsepower.
The Fast Toys High Flow 98 mm Air Lid is the highest flowing air lid on the market and the only one that works with a GM MAF with no reduction coupler required!
The Fast Toys high flow lid features our exclusive "Power Bulge" design to increase the air lid volume substantially and provide a smooth air flow transition flow from the horizontal air filter to the MAF sensor. This lid installs on the stock factory lower air filter base. A MAF is required (sold seperately). The Fast Toys high flow air lid can also be used with the stock sized MAF or our Fast Toys Ported MAF ends with the purchase of the MAF adapter gasket.
The Fast Toys High Flow Air Lid will work on everything from stock to highly modified LS1 motors. Best results will be on the modified cars that require more airflow than the stock lid and MAF combo can provide. For the ultimate performance, use the air lid with our Fast Toys Ram Air Kit (FTRA).
Note: 2000-2002 cars will still be required to use a K&N breather filter for the smog pump (available at extra cost).
Why Use The Fast Toys 98 mm Air Lid & 85 mm MAF?
What people commonly refer to as an "85 mm MAF" is actually larger than 85mm. The OD is actually 96 mm and the ID is 90 mm. Starting is 2001, GM added the 85 mm MAF to it's highest performing engines (Corvette LS6, Corvete LS1 etc). After 2002, all GM V8 cars and trucks use the 85 mm MAF for better performance.
Unfortunately, 98-02 LS1 Camaro's and Firebirds were stuck using the smaller MAF which has an OD of 88 mm and an ID of 74 mm. This is not ideal for the best performance. On our flow bench, the Fast Toys Air Lid flowed 14.5 % more than the most popular aftermarket air lid!
To work with the 85mm MAF, the Fast Toys High Flow Air Lid features a giant 98 mm ID. This makes the ID of our lid about 9-10 mm bigger than other aftermarket lids. Since area is pie R squared, the outlet area of our air lid is about 20 % larger that what is currently available from other manufacturers. On our flow bench, the Fast Toys Air Lid flowed 14.5 % more than the nearest competitor!
On top of that, we have significantly increased the overall volume of the air lid compared to everyone else. Higher volumes support larger horsepower and torque improvements. The Fast Toys air lid has 14 % more volume than the most popular aftermarket lid and a whopping 27 % more volume than the stock lid (baffles removed)!
Testing on a mild cam, bolt on stock cubic inch motor, the installation of the Fast Toys 98 mm air lid resulted in a .9 MPH increase in the quarter mile! Stroker, heads/cam and more powerful motors will benefit even further from the increased air flow. Imagine what motors running speed density tuning without a MAF can gain!
The Ultimate Air Lid For Speed Density Tuners
For those of you that have moved to a speed density tune (SD) and removed the MAF sensor, this is the perfect air lid for you! Connect the Fast Toys High Flow Air lid directly to your throttle body for the best flow possible! The OD of the Fast Toys 98mm Air Lid is 103-104 mm.
No IAT Hole
Most 85mm MAF's have a built in IAT (incoming air temperature) sensor. Because of this, we do not pre-drill an IAT sensor hole for the factory detached unit. This gives you a nice clean installation! Instructions are provided for those people that will still be using the factory sensor.
The Ultimate Performance Package
For the ultimate intake performance, combine our high flowing 98 mm air lid with our Fast Toys Ram Air Kit (FTRA). The FTRA is designed to bring cool, high pressure air into the motor to maximize performance. Since the FTRA is reliant on a free flowing air lid, this combination yields substantial performance improvements. Customers have reported up to 1.8 MPH 1/4 mile increases with the installation of these two components. That's power you can really feel!
2000-2002 LS1 Camaro/Firebirds require a K&N breather filter for the air pump hose. If you don't already have one, you will need to add this to your purchase. Easy clamp on installation.
SLP 85 mm MAF
If you don't already have an 85 mm MAF, you can add an SLP 85 mm MAF to your order. This is a high flow MAF that comes with an adaptor to work with the stock harness and weighs 1 lb less than the stock MAF. This unit will flow 90 CFM more than stock (895 vs. 805). With the screen removed (not recommended for street use) it will flow over 1000 CFM! Tuning is required for maximum HP gains and to match your engine combination.
High Flow Re-Usable Air Filter
Why pay 50 % more for the competitions performance air filter when Mac can provide a filter with superior performance for a fraction of the price?
Mac air filters are made of woven cotton fabric between two layers of wire mesh screen. The screen and fabric create a grid like effect which actually straightens and smooths the incoming air. This results in more power and better economy.
When taken care of properly and cleaned/reoiled as required, you may never need to purchase another air filter for the life of your vehicle.
MAF Adapter Gasket
To use the Fast Toys High Flow Air Lid with the stock sized MAF or the Fast Toys ported MAF Ends, you will need to purchase this adapter gasket. It can be removed easily should you ever upgrade to the 85mm MAF. This allows you to grow into our airlid as you continue to upgrade the performance of your vehicle.
3-5 Wire MAF Adapter Harness
All 85mm GM MAF's have a built in IAT sensor. However, to use this sensor with your stock wiring harness, you will need to purchase this adapter. This adapter plugs into the factory MAF and IAT harness on one side and to the 85mm MAF on the other side. Once plugged in, the built in IAT sensor will function and you will no longer need to use your factory detached IAT sensor.
