Ive got a 99 GMC Sierra with the 5.3l engine. Anyone have any experience or opinion on adding a cold air intake? Any brand that is better? is it worth the price? Thanks

Some people think CAI are a waste of money and not to waste your time and money with them. It is all up to each person.

I like mine and love the sound didn't see much improvement as far as MPG but did notice a much more responsive throttle.

There are lots to choose from, I went with S&B

 

Best of luck

Cheapest no-name one and ebay, then get a good quality filter for it.

Just from my past experiences, I had an 01 with a 5.3 and a K&N cold air intake. Worst decision ever after talking to my mechanic. The oil from the filter eventually will clog your mass airflow sensor if not watched very closely. On mine it plugged, and when that does...prepare yourself for repairs. It will cause engine to start pushing in more fuel to make up for the lack of air. This in term will damage your o2 sensors, plug your catalatic converter, and the list goes on and on. Cold air intakes have their benefits, but if you are wanting a reliable one, find one that does not need to be oiled. This will pay off in the long run.

I installed a K&N on my 01 5.3 & a Volant on my 05 5.3 and I can tell you that both units were well made, fit well but did not give me any more noticeable performance. They both made more noise under load, but thats it. If you look at their repective website dyno charts, most of the "gains" come way high up in the rpm curves. Unless you are driving around town with your foot on the floor, save your $$

I would say to save your money also. If you want to change something in the engine compartment, install a airaid mit. It will clean up the engine bay area a little bit.

      Disable DRL's

      By revmanii · Posted

      I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?

      There's a bunch of tea leaves that you've read, but in any case the delayed timing is unusual. Not sure how that relates to the rich at idle vs. 'normal' while driving.   If you're in this deep, might be worth investigating, and re-learning the sensor. What have you got to lose? Plus, it properly fixes the timing cover leak.
