Powerful LS1 motors require higher airflow than the stock air lid and MAF can provide. Until now, you were stuck using a reduction coupler or fabricating an adapter to use with a 100 mm MAF sensor. This was costing you horsepower!

The Fast Toys High Flow 104 mm Air Lid is the highest flowing air lid on the market and the only one that works with the TSP or Lingenfelter 100mm MAF

Features

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 100 mm MAF sensor. This lid installs on the stock factory lower air filter base. A 100mm MAF is required (sold seperately). The Fast Toys 104 mm Air Lid is designed for highly modified LS1 motors.

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 104 mm Air Lid & 100 mm MAF?

Highly modified motors require higher airflow than the stock sized MAF and air lid can provide. We designed our lid for those customers that want the ultimate in airflow and performance.

To work with the 100 mm MAF, the Fast Toys High Flow Air Lid features a giant 104 mm ID. This makes the ID of our lid about 6 mm larger than our own 98 mm air lid and 15-16 mm bigger than other aftermarket lids. Simply put, there is no other air lid on the market that can match ours!

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)!

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 104 mm Air Lid is 108 mm.

No IAT Hole

The Fast Toys 104 mm Air Lid does not come with an IAT hole pre-drilled into the air lid. For those people that need to re-use the factory IAT sensor, instructions are provided on how to drill the IAT hole in the air lid.
