Description
A Cold Air Intake System positions the filter outside the engine compartment to ensure the coolest possible air inlet temperatures. Cooler air contains more oxygen, leading to a more powerful explosion in the combustion chamber, resulting in increased horsepower and torque. However, this is just one aspect of the power equation. Adjusting the length and diameter of the inlet pipe to harmonize with the engine's resonance helps push more air into the cylinders (consider your engine as a large air pump). This tuning enables the system to provide maximum power gains across the entire RPM range.

FAQS
1. What a cold air intake does?
With a cold air intake, you can expect the following from your vehicle:
- Improved horsepower
- Improved acceleration
- Improved Sound
- Improved mileage
2. Does a cold air intake increase mpg?
A suitable amount of air is necessary for good and better combustion. More air can be used in a vehicle to increase horsepower. Therefore, cool air intake undoubtedly increases your car's MPG and aids in petrol savings. A cold air intake is consequently installed in your car to improve airflow and cool the combustion engine.
3. How much hp does a cold air intake add?
A cold air intake increases the amount of air that an engine can take in and resultantly the performance of engine upgrades. There is no direct number quantifying how much horsepower is added to the engine after this upgrade. But, this upgrade can provide a gain of around 5-20 hp. However, for turbocharged and supercharged engines the power gain is outstanding.

Frequently Asked Questions
What is a delete tuner?
A delete tuner is a device that reprograms yourtruck's ECM (computer) to turn off emissionssystems like the DPF, EGR, and DEF, allowing yourtruck to run without those components
Can l use a delete tuner withoutphysically removing TheDPF/DEF/EGR parts?
You MUST remove your DPF(Diesel ParticulateFilter), as the filter will clog and stop all exhaust flowwhen shut off. You will no longer need DEF(DieselExhaust Fluid), and you may remove your DEF tankif you wish, or it can sit empty. The EGR may remainas is, but we recommend removing the physicalparts as well.
Is a Delete Tune bad for mytruck's engine?
Quite the opposite. In fact, many customers reportimproved engine life, smoother shifting, and betterfuel economy (typically 3-5 MPG gains) when usinga quality delete tuner.
What's the difference between adelete tuner and a delete tune?
The tuner is the hardware device. The tune is thesoftware file that gets uploaded to your truck's ECM.Your delete tuner includes a delete tune when youpurchase from us.
Do delete tuners void my warranty?
Yes. Any emissions-related modification, includingtuning, can void the manufacturer's warranty. Manycustomers wait until after their warranty expiresbefore deleting.
Do l need a mechanic to install thetuner? How long does installationtake?
Not necessarily. Many of our customers install their delete tuner themselves in under 30 minutes. We include easy-to-follow instructions, and our support team is available if you need help.
Will my truck pass inspection oremissions testing with a deletetuner?
No. Delete tuners disable emissions systems, so your truck will not pass emissions tests in areas where they're required. Some states have exemptions (e.g. heavy-duty or rural-use trucks).
Can l go back to stock afterinstalling a delete tuner?
Yes. However, in most cases you will have to have the ECM flashed at the dealership. If this is a concern, contact our team and we can explain further.
Is the delete tune VlN-locked?
Yes. All delete tunes are VIN specific and will only work on one truck. The tuner (hardware device), may be used on multiple vehicles for diagnostic or monitoring purposes where applicable.
What support do l get with my tuner?
We offer lifetime customer support, step-by-step install guides, and remote help from our tuning team. You're never left hanging, even after the sale.
