The BBK Cold Air Induction System is available two ways: as a fenderwell mount or with a conical filter. We chose the fenderwell mount so we could feed our little Henry nice, cool air. Each system includes a K&N filter.

You will need to remove the factory airbox and intake hose in order to install the BBK Cold Air Induction System. If you choose to stick with the mass air meter you have on the car, you will not have to remove it. By the way, the Cold Air Induction System is available for speed density-equipped Mustangs as well.

Install the fenderwell mount. Use the supplied tubing to connect the mass air meter and the intake air tube to the throttle body. Notice we removed the mass air meter bracket completely with the kit. For a clean installation, face the clamps downward so it doesn’t look cluttered. We were going to change mass air meters so we didn’t do that at the time, however we did do it later.

When everything’s in place, make sure to connect the mass air meter and you’re done. We did have to trim the air intake tube in order to make the Pro-M Bullet meter work. That’s not necessary if you’re using the stock meter. Combined with a Pro-M Bullet, the two components go a long way in sprucing up the underhood area.

Just about everyone has some sort of aftermarket air induction on their Mustang. If you're a regular reader of 5.0, chances are that original equipment paper filter was trashed after just one day of service and replaced with a K&N. That's common. And while the performance gain by just installing a K&N has been well documented, the factory airbox and air intake still remain. This is one area that needs to be spruced up a little. That's where BBK's Cold Air Induction System comes into play.

BBK's Cold Air Induction Systems are available for '87-'99 Mustangs and each kit includes a K&N filter. There are two variations of the Cold Air induction System: as a fenderwell mount or a conical K&N filter-style. We installed a fenderwell system on our '93 coupe to see if it would give us any added horsepower over our K&N panel filter with the silencer removed. When we purchased the coupe the silencer had already been removed. We first dyno'd the car in this form. Then we added an old K&N panel filter. That got us just 1 hp and 1 lb-ft of torque. Bear in mind this was with the stock mass air meter and throttle body.

We tried the BBK Cold Air Induction System two ways: with the stock mass air meter and with a 75mm Bullet mass air meter from Pro-M. With the stock meter in place and the Cold Air kit installed, we didn't gain any horsepower, but we did get more than 4 lb-ft of torque. Of course, the gains would likely be larger with the car moving and a steady flow of ambient air charging into the K&N filter. We didn't really expect to gain horsepower, and BBK doesn't sell it as a part that will boost horsepower. However, with the Pro-M 75mm Bullet we gained 6 hp and another 4 lb-ft of torque.

Was this gain simply a result from adding the Pro-M? That's obvious, but the real reason we installed the Bullet was to get the continuous chrome look from the fenderwell to the throttle body. Now all we need is a polished throttle body and some other pretty stuff under the hood and we'll be ready for the show field. Combine the cost of the BBK and the Pro-M Bullet and you come up with a cash outlay of $370. That's a pretty reasonable investment for the horsepower gain we attained. The BBK Cold Air Induction System looks great, and if you can combine it with a larger-than-stock mass air meter, you will gain increased performance along with killer good looks in the underhood department.
