Once the exhaust has been freed up, more air can be removed from the engine than is being inhaled. Increasing the volume of air into the engine will increase your horsepower. The more air that reaches the cylinders, the larger the combustion and the higher the power output.

Unfortunately, there are not many aftermarket options as far as intakes for the Probes. The cheapest, easiest, and least improving intake mod is a simple K&N drop-in replacement for the factory air filter. The filter flows slightly better than the factory one, but the real bottleneck is the factory air filter box itself, so the improvement is negligible.

An excellent and cost-effective intake mod, is to buy a K&N, GReddy Airinx, or Racing Sports Akimoto filter and attach it directly to the front of the VAF sensor. Scott Streeter has an excellent set of instructions on how to do exactly this. Take a look at his page for further details.

HKS makes a Power Flow intake for the Probes. The kit consists of a mushroom-shaped filter and a short tube that is used to attach it to the VAF. This filter is supposed to flow a little better than the conicals, but the element is made of foam and I have heard that it may be prone to disintegration from various cleaners and / or engine fluids. Retail price is about $180.

Since these were the only choices at the time, I personally had an intake custom fit to my Probe GT. The kit that was used was from Racing Sports Akimoto and was for the '92+ Honda Prelude. Since that time, RS Akimoto has started producing intake kits for the 2.0L Probes. From what I understand, both the 2.5L and the 2.0L engines use similar intakes, but they are not directly interchangeable.

Also, as of late, Hotshot has begun producing a "cold air induction tube", similar to the one on the photo, for the Probes. This pipe attaches to the front of the VAF and bends down towards the opening in the splashguard. A conical filter attaches to the end of it and hangs about 1" under the bottom of the splashguard. Have a look at the Hotshot cold air pipe installed on my Probe.

Recently released is the PRM intake. Although I haven't personally seen it, my sources tell me that it is as good, if not better than the Hotshot. Better as far as design, not necessarily performance. It is similar to the Hotshot cold air pipe in that it connects to the VAF and makes a turn for the splashguard. However, unlike the Hotshot pipe, the "Jet Stream Filter" is directly in front of the VAF (where PRM is printed) and the bottom is open with a water-repelling mesh web across it. Retail price is $189.00

Since many Probers are purchasing intake tubes to go between the VAF and throttle body like my original setup, there have been some questions regarding how to fit it to the back of the VAF. Here is how mine is connected.

I have had several different intake setups in my own Probes, including the Hotshot cold air pipe. You may wish to take a look at them in order to get some ideas on how to fabricate your own.
