Fast Toys High Flow Air Lid, 98mm 98-02 F-Body


Fast Toys High Flow Air Lid, 98mm 98-02 F-Body

Calculated at checkout

Product Description

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 an 85mm MAF. Both of these restrict airflow and cost you horsepower.

The Fast Toys High Flow 98mm Air Lid is the highest flowing air lid on the market and the only one that works with an 85mm 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 85mm MAF sensor. Provisions for the stock IAT sensor are provided. This lid installs on the stock factory lower air filter base. An 98mm 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 (see below).

The Fast Toys High Flow Air Llid 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). Why waste your money on a stock sized air lid that you will eventually have to dispose of when you need to upgrade to a larger size MAF or Speed Density tune?

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 Air Lid & 85mm MAF?
What people commonly refer to as an "85mm MAF" is actually larger than 85mm. The OD is actually 96mm and the ID is 90mm. Starting is 2001, GM added the 85mm MAF to it's highest performing engines (Corvette LS6, Corvete LS1 etc). After 2002, all GM V8 cars and trucks use the 85mm MAF for better performance.

Unfortunately, 98-02 LS1 Camaro's and Firebirds were stuck using the smaller MAF which has an OD of 88mm and an ID of 74mm. 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 9-10mm 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 85mm 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 Ultimate Performance Package

For the ultimate intake performance, combine our high flowing 85 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!

Optional Accessories

Breather Filter

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 85mm MAF

If you don't already have an 85mm MAF, you can add an SLP 85mm 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.

Important Installation Notes

1998-2002 Camaro SS

Factory and afermarket SS hoods may experience rubbing on the hood. This can be addressed by putting some adhesive tape or the soft adhesive velcro in the contact spot to prevent paint scuffing. This same problem occurs with SLP and other aftermarket lids as well.

1998-2002 Camaro Z28

Some models of Z28's with the factory hood may experience problems closing the hood. We've had some people with no problems and others that said they couldn't close the hood. To rectify this problem, the bottom of the air box assembly will have to be trimmed and the hood contact point may need to be trimmed or flattened. If you experience this problem and do not want to modify your vehicle, you can return the lid to the manufacturer, not the retailer, for a refund. Please note that shipping costs are non refundable and the goods must be in new condition (no marks or damage).

1998-2002 Firebird, WS6 and Firehawk

No reported issues of any kind.

Aftermarket Hoods (other than Camaro SS)

No reported issues of any kind.
