Any recomendations on cold air intake my old LPO advised me not to ge K&N, cannot remember the reason why but was looking at others and was unsure like AirRaid or Spectre or InJen any thoughts which one i should use i own a

and should I get a throttle body spacer with the cold air intake?

 

No experience with the CAIs, but definitely do not get a TB spacer. Unless, of course, you need a very expensive paperweight for your office.

If our trucks were TB injected, like the really old vehicles, a TB spacer would work. However, that has not been the case for a few decades, so a TB spacer is worthless.

Which LED tailights do you have? Any pictures of them and your truck?

 

Not completely worthless. My Jeep had one when I bought it and it made a really neat whistling sound when I stepped on the gas.

 

I'm very happy with my K&N Intake. I have the 63 series with the plastic tube. I'm not into cleaning chrome under the hood, plus it gets more power than the metal anyway.

I'm not sure why you're guy would recommend against one. The only reason I can think of is that back in the day, K&N had some recalls on some of their tubes because the design they were using was prone to having pieces of the tube come off inside and go into the engine. Those days are long gone though.

 

There is not a true "cold air" intake, the air comes from the same place as the factory set up basically. Get a cheapo ebay one or better yet, make your own. Dont pay the ridiculous price for a brand name unless you just have money laying around. Also, dont be afraid to use the search function. This topic has been covered many, many times. For example:

Here's how to make you own:

Welcome to DF.

 

I Have a K&N cold air intake (plastic one) and I love it. I think i got mine on Amazon for close to $200 shipped.

 

A cold-air-intake is a misnomer for the most part, it's nothing more than an outside air intake with fewer restrictions than OEM and, in my opinion, not worth a couple of hundred bucks that most retailers sell them for. I see a lot of people wrapping the tubes with insulation, but unless the tube is lying on an exhaust manifold, the air flow is so fast, it doesn't have much time to absorb any of the tube heat to make any difference. The 2 biggest things to keep in mind when making or buying one are:

• Tube diameter - I generally go for an "overkill" of about 3" for most engines.
• Tube style - a smooth interior surface (as smooth as you can make it) is recommended. The accordion style tubes/hoses are easier to work with but they cause a lot of air flow restriction. Each wrinkle causes turbulence, and they all add up to greatly restrict the effective air flow diameter of the tube. I tend to use ABS tubing - it's very easy to weld using standard plumbing tube, connectors, and solvent, and you get a fairly smooth interior.

 

I have the 77 Series KN and its been a nice addition! I have had no issues with it.

 

I have a K & N also and other than the distinctive noise, i am real happy with the added responsiveness of the throttle.... still getting crappy MPG just like everyone else...I might add a little sound proofing if I can figure out how....ha ha
