Sounds like an S&B CAI but not sure. I would definitely look into replacing the cold side intercooler pipe since the OEM pipes are notorious for blowing. I would also consider installing a CP4 disaster kit as well. As for the mileage, 98k isn't much at all so no worries there. Without knowing the history of that truck, I would suggest you do a complete tune-up (clean/replace air filter, oil change, fuel filters, rear diff fluid, front diff fluid, transfer case fluid, and trans service) just so you know where everything stands. If they've never been done, it's time anyways. Drain your fuel/water separator every two weeks, change your fuel filters every 15k miles, always use a reputable source (Shell, Exxon) for your diesel, find a good diesel additive and use it with every fill-up. Don't use cheap products/fluids with your maintenance. It does make a difference.

Good advice, thank you sir. It is an S&B CAI. Just had the oil changed today. I need to find the fuel/water separater, didn’t know about that.
I freaking love this truck so far.
Only problem that I’m having is a real bad jerk, I noticed it does it about every other time at about 27mph when auto trans is shifting from 3rd to 4th. I took it back to the used car dealer I got it from and he says it’s probably the tune. His son is going to try to help me tomorrow on how to adjust the tune for the transmission or something.
Today I got on the gas pretty hard from about a 35mph roll and it jerked so bad that I though it tore up the transmission. Scared me, that’s a no go and I got to get that fixed ASAP.
I did notice today it has the EZLynk box plugged into the ODB2 port and zip tied under the dash. I downloaded the Auto Agent app on my iPhone and was looking at the settings but I can’t adjust or see any tune files. Says I need to link with a tech.
I’m confused haha I just want it fixed. I find it hard to believe the previous owner drove it like that. Wonder why he didn’t fix it before trading it in?
Also it is an aftermarket exhaust but no name anywhere. Dealer said it already has the DEF delete. I’m curious what all has been done to this truck performance wise.
