Cold air intake

I put a k and n Blackhawk cai in my 2011 mustang and it’s running smooth but it will dip in rpms like 20 rpms but then go right back to normal. Is that normal I did a idle relearn and have no leaks

Go back to the stock "CAI" and see if anything changes.

And FYI it was a waste of money buying it in the first place.

Free doesn't mean you should use it. It's not as good as the stock "true" CAI. Put the stock unit back on and sell that worthless crap.

How far have you driven your car with the CAI on it? It may take a couple of 100 miles and several cold starts for the mass air and computer to relearn the intake strategy and mixtures.

I’ve only driven it maybe 75 miles it does fine unless the air is on then it will only do it every once in awhile It drops like maybe 100 rpms then it smooths back out and if the air is off it runs perfect

Its not that he doesn't "like" CAIs, its that what you are describing is exactly what happens when you mess with the air intake tract and don't get it tuned. Not to mention he is also correct about the power gain being nil. If the car came with the OEM air intake, put it back on. If not then go get it tuned asap. And like I said in your other post, take it to an actual dyno tuner or get a legit remote tune done on it. Bama and Steeda "tunes for life" are canned tunes and especially Bama tunes can be downright dangerous to run.

CAI erratic rpm.

I agree that it's a fact that after market CAIs are a waste of money.

Do you have the stock grill? “Open” grills can create turbulence going into the air tube and mess with the MAF. A Tune won’t solve that issue. It will happen at certain speeds but shouldn’t happen at a standstill. If you suspect this, you can stuff a T-shirt or cloth in the inlet to the air box, go for a quick ride and you should notice the difference right away. If there’s no difference then you should either go back to the original or data log and get it tuned.

Reading comprehension seems to be lacking for both of you. I tried helping him with my first post and all he wanted to do was argue.

What is this "#fakenews" now? I'm assuming I'm the other "know it all". I was very nice to him in the other forum he cross posted in and cordial in this thread too. What are we supposed to make **** up and lie to him to make him feel better? He got a worthless part on his car and we are telling him to remove it and go back to what works. Seems like its becoming the norm for ppl to rather feel like they were right than admit a mistake and learn something...

We are.

Part of that is giving actual advice even if that hurts someone's feelings. I dunno how many times on how many various forums you can tell someone correct information but they will ignore it because that's not what they wanted to hear. For whatever reason.

Someone spends $300+ on a cold air intake and would rather bolt it on and cause issues than admit they made a mistake getting it and sell it for a loss or just eat that $$$.

I hear what you’re saying Scotty, no argument there. Sounded like op wanted to keep the cai and find a solution that would allow him to keep it. Certainly plenty of ppl use them w/o issue or remedy the issues they have and I think that’s what op was looking for. Truth does hurt sometimes but some ppl enjoy it lol.
