Air Intake Demo for 2006 and 2007 Chevrolet Trailblazer

K&N has designed a performance air intake system for the 2006 and 2007 Chevrolet Trailblazer with the 6.0 liter engine. K&N dynamometer tests show a 19.18 horsepower gain at 5330 RPM with use of this K&N air intake modification. K&N tests multiple vehicles for each air intake kit it makes to ensure a consistent horsepower and torque gain. This video features a power gaining K&N air intake installed on a 2006 Chevrolet Trailblazer with the 6.0 liter engine. Refer to each intake's instruction sheet for full installation details.

A local tuner has dyno tested this intake and its actually worse than the stock intake. It smoothes the airflow, but sucks in hot air from the engine bay and blocks off the only source of cool air. The engine fans are not producing cool air as stated. They are pulling hot air from the radiator fins, which is exactly NOT what you want being introduced into a cold air intake.

@Mach1Spd This is quite a statement to make. Do you have any of the data proving this? I have spoke with my product manager and he is more than happy to look into this if you or the dyno shop can provide actual dyno pulls, intake air and EGR temperatures. We publish our dyno chart showing the 19+ HP we gained from this kit and back it with a HP guarantee for our consumers.

[Mach1Spd]

@KNfilters Yes. I can send the data to you if you like. Also, it is very bold of KN to claim a 19 HP gain simply by bolting this intake on. Its not possible. I picked up 20 WHP from custom dyno tuning, and that was only achieved by bumping the timing up from the stock 18 degrees up to an aggressive 24 degrees. You guys are claiming the same gains as an aggressive tune or even headers. Only a 4" intake with LS7 MAF will get near those gains, and only with tuning.

@Mach1Spd I can assure you we do not fabricate our dyno results. We test our kits on a number of vehicles and do many pulls on each vehicle and only publish the pull from the middle reflecting the average. Our record high HP gain for a stock production vehicle is 56.96 HP at the wheel. Our product manager would like the information you have from the dyno pulls, if you can contact me at 800-858-3333. Thanks.

@KNfilters ieatsrt8 is the most popular intake for the trailblazer ss. compare the 2. i would like to see you guys offer a better unit for the tbss communtiy. as of now most of the forums are against using the k&n intake.

@BLACKLACDTS ...all dynos are not the same. We actually have the most advances dyno in the country, so our pulls are more accurate than any competitors. The primary reason we don’t use the vent on the vehicle is because at high speeds the air hits the filter with too much force creating turbulence in the system which causes a CEL. This doesn’t happen with all the models, but it does happen with a significant amount so we eliminate the vent to prevent it.

@BLACKLACDTS You are correct that hot air=less power; but you are talking about a small difference. More restriction also equals less power. Our system actually makes up more power from restriction loss than the few degrees in temperature could. We actually got over 19 HP increase on the dyno with our kit, which proves it works. I am willing to compare our kit to any competitors if you can provide the info of the kits. Keep in mind, different dynos will actually give different ratings because...

@KNfilters the cold air that comes in the duct is wasted due to the wall of the k&n system which is enclosed when the hood is shut and could benifit from the "duct". your saying the system uses the hot engine bay air but thats what its supposed to be avoiding.hot air= less power. compared to competiters your kit is restrictive. it gets thin to fit under the engine cover. tbss forums dont recomend the kit. it needs more R@D to optimize potential. i hope you guys check into this.

[KNfilters]

@BLACKLACDTS The “cold air” duct only works if there is a enclosed filter. When using an open element filter, the “fresh air” is not forced into the intake. So the “fresh air” duct serves no purpose when using an open element air system. Keep in mind, there is always fresh air flowing through the engine bay, drawn in by the fans on the cooling system. We pick up our HP from reducing restriction, not cooling air.

i challenge k&n on there trailblazer kits. its not made correctly. i have 1 on my truck and it cuts off the main cold air flow designed into a trailblazer ss. please k&N challenge me on this.
