    Hey All,

    1st post.

    I installed a custom made cold air intake today using Spectre parts and a K&N filter. I mounted all of the vacuum hoses and sensors that are on the stock system.

    After starting it up I noticed the check engine and track control dash lights are on. Everything is running fine and I notice an increase in power.

    Any info as to why the lights are on would be appreciated. Thanks!

    Ken

    Roll to an AutoZone and get them to read the code (or if you have a scanguage use that). Knowing what code the ECU is throwing will help ALOT.

    I don't know about an increase in power is noticeable but you porbably noticed better throttle response. You probably have a maf leak or something to that sort.

    Did you unplug your battery while doing this?

    Could be your MAF sensor has oil on it from the K&N filter. Get some contact cleaner to clean it off.

    Most "cold air intakes" are misleading to begin with. If the filter is an open element (you can see the filter) and it's under the hood, it is actually a "hot air intake" (in other words - they lie and sell you something). When was the last time you ever felt a cool breeze under the hood of a car/ truck? A true cold air intake has to take in air from an ambient source - aka outside the engine bay. If you want one that bad for the "cool factor", or if your car/ truck doesn't breathe from outside the engine bay, find one that fits that description.

    The air that the OEM (the one it came with from the factory, or Original Equipment Manufactured) air intake breathes in is usually from just behind the grille itself, or sometimes from a fenderwell. This "air charge" is actually cold (or ambient temperature air), as hot air will just drop your ignition timing (because of pre-ignition or detonation) as the temperature of the intake air increases, and take all your HP with it.

    Let common sense help some on deciding just how good an aftermarket part or system is:
    1) Why would the Manufacturer short you on the performance it could have for an extra $100?
    2) If you gained MPG with a simple piece of tubing and a "one size fits all" air filter element - wouldn't they do that at the factory that built the vehicle?
    3) Who do you think has more money and resources for Research and Development - the company that designed and built the entire vehicle, or the company that made that "cold air intake"?
    4) If something you could buy and install yourself would actually add HorsePower and MPG, why would any vehicle manufacturer waste millions designing it the way they did (and lose the edge on the competition)?

    Add to that the water protection that a stock OEM air box is designed to provide. Water intrusion is a HUGE concern to prevent damage, and here's the reason, air compresses and water doesn't. If an engine breathes in water, and tries to compress it, it will break in a big way.

    Some "cold air intake" kits have a water intrusion valve that is basically a ping-pong ball in a sleeve - good luck trusting an engine to that. I know where they got the R&D on that design, just open up a wet/ dry shopvac and you'll see the same thing. Amazing how brilliant these things are when you dig.

    I brought it to autozone to have the code read. Turns out the incoming air temp was too low. apparently this is a semi common issue when putting on a K&N filter.

    So I called K&N and they said just clear the code and it most likely won't come back once the computer adjusts its self.

    Thanks all.

    Not trying to ruin the party, but alot of air boxes design also eliminates induction noise. Certainly the manufacturers have to consider power, emissions, and fuel economy. However, everythings a compromise to think that removing the OEM equipment will not give you any power increase is wrong. Folks just need to understand the power increase may not be in the power band that they're using often, and the increase in power will be modest at best. The biggest plus I see for intake kits is they open more space under the hood and slight increase in fuel economy if they keep their foot out of the gas. Removing the restrictions designed for noise reduction frees up the air flow allowing for the increase in power wether cold or hot air.
