The number two complaint about the 996 is that it’s too quiet. (Number one is about those #@%! headlights.) One popular upgrade to improve sound as well as performance is to install a cold air intake. Today, we’ll assemble and install the Fuel Injection Performance Kit (FPIK) from K&N.
K&N claims that this intake will add about 24 hp and 23 ft lb of torque to an otherwise stock 996. Since we’re in it for the noise, any boost in hp or torque would be welcome, but we aren’t expecting anything noticeable on the butt-dyno.
Once you unpack the box, you will start to realize that some assembly is required. For the price of this thing, you’d think they could have done much of the major assembly at the factory. But you’d be wrong. Think “gas grill” and you’ll get the idea. At least we managed to assemble it without (many) extra parts.
The kit does include instructions including this technical drawing that’s just a bit too small to be truly useful, and step-by-step instructions which generally do not include part numbers. Instead it has the not-so-handy phrase to assemble XYZ component “with the hardware provided”, referring back to the aforementioned diagram. But you’ll get through it.
As best we can tell, most of the parts were there, and the steps were correct, except for one bolt which is incorrectly labeled in the diagram, but correctly shown in the accompanying photo. And one hose clamp is too small. Give yourself about an hour to assemble everything, then about an hour to fit it to the car.
You do have to drill three holes: two in the plastic fresh air supply duct from the stock air box, and one in the car to hold a bracket. I wasn’t too happy about that last one — these thing should be fully reversible, but in for a penny….
Actually fitting it in the car was fairly simple. Don’t forget to pull the rubber boot back on the MAP connector so you can flip the connector around and not bind the wire. It took about an hour to fit it in the car, mostly because the duct from the stock air box took some finesse to fit. Here’s a helpful hint: Raise the spoiler so it’s easier to see if the trunk lid and the duct are actually lining up. I had to bend the connector to get the duct in the right position.
So what do we like about it? It looks cool. This is how your Porsche is supposed to look when you open the engine cover. Even if it doesn’t help with performance, as long as it doesn’t hurt, I think we get some style points.
Dislike? Hidden in the product description is that it shouldn’t be used in harsh weather. Not really sure what that means. A heavy downpour? 100 year flood? Swapping back to stock is possible, but not that easy. We’re trying the DryCharger cover which offers a certain level of protection from splashing and will try to find a conical shaped cover.
A few thoughts about the stock box. If the dirt pattern on the old filter is any example, it doesn’t draw very evenly across the filter. The narrow part of the filter had hardly any dirt. The dirtiest part was where the stock box was open on the bottom to the engine compartment. This filter has only been in the car for six months.
While you’re doing this, consider checking (and changing) your belt and if your engine is a mess, wash your engine. You’ll feel better knowing your motor is clean. FYI the stock belt is K060832 and available at your local NAPA auto parts store.
