5.0 out of 5 stars Good cai..! Not the best, but for the money it’s like a sore pecker, ya can’t beat it.

Overall for the money.. it’s a good product. I didn’t agree with how it was packed but it was only rubber. A little time by heat vent, and your all good.With a throttle body spacer you need to trim the shroud, it’s nothing. It’s plastic!!It’s pretty loud, not a whistling noise, but when you rev it, on the up-rev you can really hear it sucking.It didn’t improve gas mileage to my knowledge, maybe .02 of a gallon..However it does quicken throttle response.You do need to use one of your stock rubber connectors over by the map sensor.You’ll figure it out if you can put two and two together....

Easy to install I had to cut 4in. off so my maf sensor would fit in before the intake housing but wasn't a problem at all to cut.

2004 suburban, this is a knock off of the spectra, but i wasnt going to pay $250 after my $300 3in bully dog air intake broke at filter connection. If u have a gm MAF with notch youll need to buy the MAF spacer, spectre spe990003 , also youll need at least 3 inch long 4id coupler, the one they provide is too short. Also youll need gm MAF adapter 25171042, if yours is old. Also youll need #10 ×4in long bolt and hardware. I used wing nuts so can tighten with fingers . The support bracket is was welded on to far back. Probably why this so cheep. Factory reject. So after some adjustments i made it fit. . I have at least 2in of pipe in the 90degree rubber elbow, red sharpie mark Maf sitting center houseing, abiut 1inch clearance between filter end to fender

Not sure if it increased any horsepower but it takes various upgrades to actually see any gains. It does sound throatier when accelerating and I think the engine is getting more air. Dual exhaust and other mods will certainly help increase performance.

For the price, can’t beat it. But beware, it will not drop right in. Mine didn’t at least. Had to manipulate the tube and box a bit and the rubber ducting doesn’t fit the stock mass airflow sense worth a damn, so that was a chore to get it to seal right…ended up using the flew duct from the stock set up but then the air filter barely fit. The tight fit meant no moving of the filter tho so I guess that’s a plus? 🤷🏻‍♂️. Anyway, can’t beat the price but if you are a perfectionist, spend the money and get a proper kit.

I recieved the package in record time. Was packaged very nicely. Took a bit of time about an hour and a half...was a little stumped with the air mass flow sensor coupling but figured out that you have to slid it all the way to the notches and clamp the heck out of it. Only issue is the check engine light came on when I was driving on the freeway. I will check all the connections and clean the mass air flow sensor and hope it goes away. Other than that I can definitely hear alot better flow to the motor.

5.0 out of 5 stars Good CAI for the price

Reviewed in Canada on August 9, 2020

So far so good. Easy installation. Took about 15 minutes to install. Noticed the flow gain over stock air box. No modification needed on my 04 Silverado 1500 Z71 Extended Cab. Needed to reuse 1 clamp for MAF sensor (see 2nd picture).
Overall, good cold air intake for the price.

Cons: clamps that come with this kit are fairly cheap.

Don't waste your money. Sais it's ''silicone boots and not the cheap rubber one'' which is not the case at all. Contact seller a month ago and haven't heard back yet. Does not fit at all from MAF sensor to boot..... not even close to fitting.

What cold air intake gives the most horsepower?

What Cold Air Intake System Gives You the Most Horsepower? If you're looking for the greatest increase in horsepower, choose the K&N 57 Series FIPK Air Intake, which is legal in every state and includes a washable cotton air filter.

Is a tune necessary for a cold air intake?

Yes. To put it simply, anytime you modify the airflow in an engine you will need a custom tune to compensate for the change. There are intakes that don't modify the airflow enough to where you need a custom tune so identifying which one you have is important.

How much HP does K and N cold air intake add?

However, K&N intakes typically add an average of 15-25 additional horsepower over a stock system**. Each kit undergoes significant testing to help ensure that the filter and intake tube are positioned to deliver large increases in airflow and horsepower.

Will a cold air intake make my truck run better?

Most experts agree that cold air intakes do improve truck performance, and this improved performance results in better fuel economy thanks to the more optimal airflow that intakes can boast. In fact, many truck owners report an increase of 1-2 MPG after installing a cold air intake system.
