Marvin I figured I'd post this again so people can learn about Place Racing incase they have a few Questions
Place Racing Inc. (PRI) began developing its exclusive line of Cold Air Intakes (CAI's) more than eight years ago, when there were absolutely no products on the market of this nature. The very first intake we built was for an 89 Sentra with the outdated vertical style throttle body, almost like a carburetor. The intake consisted of twin tubes, two K&N filters and a plenum adapter that fitted over the throttle body. Of course the poor little Sentra had no real power and all this new plumbing didn't make much difference, but it sure looked trick!
All you SE-R owners really have an extremely bright and talented young man by the name of Justin Choi to thank. Justin, came to our original shop as a high school student, the same year we built the old Sentra twin tubes. Justin literally bugged us month after month to design an intake system for his car. Eventually we did fabricate several prototype units that Justin tested for us. Some of the early photos of these prototype tubes are still floating around. We eventually revised the original design to improve the airflow characteristics, and later thanks to Justin's hard work and constant promotion, he introduced us to Mike Kojima, who most SE-R owners will recognize as the author of many Nissan related Sport Compact Car Magazine articles. Mike at the time owned an impressive 200SX SE-R, the subject car of many of his articles. We designed the intake for that, and from then on, we have been in constant production of these intakes, covering all SE-R models from 91-99, as well as SE's and later adding the Altima intakes. Mike was also the motivating force behind the Maxima intakes, when he brought his Infinity I30 (same engine as the Maxima) in for prototype work. The groundwork was laid out for the current lineup of Maxima intakes, but for some unexplained reason, even after Mike's esteemed recommendations, the intakes just never sold. We were at the point of actually discontinuing the Maxima lineup which at that time only included the 95-96 applications. Brian Catts, of Cattman Performance saved the day for all Maxima owners. He artfully promoted the intakes, and provided the market for the later development of the complete lineup covering a decade of Maxima's from 89-2000. To this day Brian is the single largest purchaser of the Maxima intakes, and through his hard work, we respond to more than half a dozen inquiries a day for Maxima information.
The intakes are each hand built, using 3" mandrel bent mild steel tubing. Each kit consists of an upper tube that generally has all the proper fittings welded on to attach the OEM hoses and tubes that are found on the original stock intake system. One of the best changes that we made to all the Nissan intakes, was to incorporate an attachment point for the AMB temperature sensor. In the past, we have seen other manufacturers of intakes, just leave this out of the system or worse yet, punch a hole on the filter top and jam it into the filter! Since we were striving to get as much cold air as possible into the engine, the temperature sensor was an important part of the system, and we placed them directly onto the tubes where the sensing element would be reading the actual temperature of the cold air running through the tube, and adjust the ECU program to suit this cold dense air.
The way the intake works, is threefold. First off the intake improves performance and horsepower by smoothing out the curves and restrictions of the stock intake making it easier for the air to enter the engine. More air always means more power. Second, the intake improves performance and horsepower by lengthening and tuning the intake path. The tube is designed and bent so that it provides a pathway almost 30" long! With this length, the air inside the tube creates a ram effect that literally forces the air into the throttle body throughout the entire RPM range, but especially so above the resonance point of the intake. You can actually feel and hear the resonance point between 4000-5000 rpm, and from then on till redline it is just amazing what the intake does for these Nissan engines! Finally, the best part of the system is the cold air!. Cold air is far denser than hot air, which means there are more oxygen molecules with each breath the engine takes. All internal combustion engines always run better on a cool crisp morning. rather than on a hot sultry day. It is bad enough that the stock intake is so restrictive, but a good portion of the air ingested into the intake is hot engine compartment air. Just the air alone from the radiator is heated to 160-200 degrees! Then you have the heat coming off the exhaust manifold which can reach 500-900 degrees, and you can see that the worst place to get air is anywhere inside the engine compartment. This is why all aftermarket intakes that leave the filter cone inside the engine compartment, fail to deliver the expected horsepower gain. All Nissan engines read the temperature of the intake air, and if that air is the hot 200-300 degree engine compartment air, then the ECU is going to adjust the fuel mixture so that less fuel goes to the injectors! Less fuel means less horsepower!
While you cannot change the temperature of the air around us, you can trick the engine into thinking that it is much cooler than it really is. The Place Racing Inc. CAI locates the filter in the driver's side fenderwell area where it receives cold air from the front grill area, before the radiator and away from the hot exhaust! The air going into the filter can only be as warm as the temperature outside! Based upon what the engine is used to taking in, on an average 75 to 80 degree day, the engine thinks it is snowing outside! The AMB sensor reads this cold air and increases the fuel volume to match the denser cold air. The result is instant horsepower that you can feel and hear! Not some unfounded manufacturers claim that you never actually feel or see, this horsepower is real. Thousands of Nissan owners have invested in the intake system, and testimonial after testimonial can be found on the World Wide Web! Most of these intakes will generate a minimum of 8-10 real horsepower at the wheels! Some of the applications even generate horsepower levels up to 12-13+ hp.
The intake creates a terrific deep growling sound when the throttle is wide open. It is a beautiful sound to hear and feel, but it is in no way annoying, as it is perfectly quiet when under low load or part throttle conditions. So cruising on the freeway or around town will be just the same, but get on that throttle, and see what happens! A great way to test the effectiveness of the system is to install the system, drive your car extra hard for 10 or 15 minutes until the entire engine compartment is good and hot, then stop, turn off the engine and immediately pop your hood and feel the intake tube. It will be nice and cool, while everything else will be good and hot. Be careful not to burn yourself!
Like all intakes that place the filter in a position lower than stock, there is some danger that water may be ingested into the filter and consequently damage the engine. Driving in rain, even heavy rain is not dangerous, however driving through deep water is. Even though the filter inlet is about 15-18" above the ground, care must be taken if you drive through water deeper than the lower lip of the front spoiler. If water flows over this lip, which is generally 8" or more above the ground, it could possibly flood the compartment where the filter is. If the area where you drive tends to flood, then you must drive with caution. The best bet is to move the filter back up to the engine compartment. Since the MAF adapter is the same diameter as the filter, you can move the filter up to the MAF with only a screwdriver. In case you ever get stranded in a heavy downpour and you are faced with having to drive through water that is too deep, you can always just disconnect the lower cold air tube completely and leave the filter down where it is. Driving like this temporarily will not harm the engine as there is not going to be a whole lot of blowing dirt and dust when everything is soaking wet! Do make sure that there is no loose dirt, leaves or debris around the intake inlet though.
We only use genuine K&N filters. There are many other filter manufacturers that sell K&N look-a-like filters, but these are not of the same quality and flow characteristics as the genuine K&N. While the K&N filters are almost 3 times more expensive than these cheap aftermarket look-a-likes, we refuse to change just to save a few dollars. Sadly, even some of the widely available POP chargers don't use a genuine K&N filter. Don't be fooled by a lower price with the competition, insist on a genuine K&N filter. K&N guarantees their filters for a million miles! They recommend that you service the filter every 20-30,000 miles! The K&N filter actually works better as it gets dirty! Since the filter is made of gauze, coated with a special filtering oil, any dirt and dust that adheres to the filter also becomes coated with oil, and becomes part of the filtering element helping to trap even finer dirt particles. These filters can be washed out and re-oiled with a special re-oiling kit available from K&N or directly from us. They never have to be replaced!
