But is this really the best way to go about improving your truck’s performance? Let’s take a look at the pros and cons of installing a CAI on your 6.7 Cummins.

PROS:

CONS:

1. Can be expensive: Depending on the brand and quality of the CAI you choose, it can be one of the more expensive performance upgrades for your truck.

2. Can be difficult to install: CAIs can sometimes be tricky, especially if you don’t have experience with automotive mods. It’s always a good idea to consult a professional mechanic or installer before attempting to install a CAI yourself.

3. May not be street legal: In some states, driving your truck with a CAI is illegal. Check your local laws before installing a CAI on your vehicle.

So, should you install a cold air intake on your 6.7 Cummins? Ultimately, the decision is up to you. A CAI may be a good option if you’re looking for increased power and performance. However, if you’re worried about the cost or difficulty of installation, you may want to consider other performance upgrades for your truck.
