intake mods - 7/3/2006 2:46:21 AM

Are there any inexpensive intake mods that can be done to the factory equipment. I want to get a cold air intake but it may be a while. For the time being I may have to settle for a K&N standard filter and setting up the air box to allow more air in. Has anyone done anything like that? Any suggestions are welcome and appreciated. I just purchased the Blazer a few days ago. I'm ready to start doing a few things to it.

Any other mod ideas for the vehicle are welcome too!

go for an exhaust. they're not that expensive. u can get an aftermarket muffler and let ur car breathe a lil easier. i have a magnaflow muffler with a chrome tip. i got mine done for about 160, labor and all. if ur lucky u can talk them done too. u could get pulleys for under 100 bucks too. um...jet performance makes a thermostat thats about 15-20 bucks. all other moods that i know of r more expensive. hope that helps.

if u still have the stock airbox u can make a bigger hole in it where the air hole is at now or u can descreen the mass air

Please be aware that removing the screen on a stock MAF sensor can cause more harm than good. Stock MAF sensors are calibrated to be used with the straightening screen installed. This evens out the airflow so that the placement of the sensing elements reads the average. By removing the screen, the flow could be distrubed enough that the MAF reading would not be accurate to a point of damaging other areas in the motor AND transmission.

Also let me say that it has been well documented in the 3800 community that the screen has showed NO measurable decrease/increase in performance installed or uninstalled. Both cases being tested at the track and on a dyno. What was worth noting is an erratic idle and a lean condition that was recorded by the dyno computer. Both issues that were not there on the same vehicle with the screen installed.

Now with a proper cold air intake, a screenless MAF (one designed without a screen) that has a larger throat diameter will obviously flow better. But to ignore the fact that the factory MAF when modified does not equal a properly engineered aftermarket MAF is... Well... You get the point.

This has already gotten more long winded than I intended so I'll leave it be with this. I have had this discussion before and it can be found here:

The link above walks through the intake tract showing the relative CSA (cross-sectional area) of the restrictive components. Have a read through it if you have some time. LOL

for $30 at Autozone you could pick up the Edelbrock 14" air filter that just bolts on and you would remove the box all together. or am i thinking of the older models only? I have a 92 so i dont know about the newer ones.

Thanks for all the suggestions!!! The weekend is finally here and I'll have some time to do a few things with the blazer. I've only had it a week so its about time I got to do a little tinkering!

hey swart what about running an aftermarket MAF with a CAI. would that help any?

So long as the aftermarket manufacturer has setup their MAF frequency range in such a way that the stock PCM knows how much air is going through it, you should be set. Then your restriction is in the TB, exhaust, and cam profiles.

or you could just get something like what is posted in my link. man its always good practice to check ebay first! lol, it may not be a k&n but fo rthe cost i am sure you wouldnt mind. you could always add the k&n filter later and just use the piping from this one

no i do not have one because my truck is a 95 so it wont work with mine. however, if you want to mod your intake to take in more air this will certainly do it. will the filter flow as much as a K&N i am not sure but you are paying a fraction of the cost you would be spending on the K&N. so to me it would be worth it. especially if down the road you want the K&N you could use this piping, like i said. i am sure that the piping i showed you with a K&N will work just as good as the K&N kit that sells for 300 dollars. unless K&N uses some special intake grease to reduce friction inside the intake!

AFTERMARKET MAF IS A WASTE OF MONEY- even running 12psi i will still run the stock maf. it flows good enough 2 350hp. and the aftermarket ones are crap.

Black....not sure about the grease but I'm sure the K&N has some form of a seal to help bring in outside air and not engine compartment air. I'm gonna look into this a little more. Thanks!

Yeah I kinda thought that but you never know what people will try to tell you about vehicles. I'm not completely up to speed on the technology in the auto world either so I would hate to call someone out and be made to look like a fool. Glad to know you were joking!

ight so my brothers telling me that a short ram cold air intake does almost nothing as compared to a cold air intake with the inlet in the valence because the short ram CAI is close to the engine and after the engine warms up the air is heated, and that the valence inlet is the better choice, does he have a point

Well, right off the bat, if you have a filter open to underhood temp air, that is hurting you more than any increase in flow will help. A true CAI will out perform a filter on the TB in any instance (all external sheet metal installed and unaltered). The colder the air, the more dense, and the more potential to make power.

With my supercharged Bonneville, I can tell the difference between an 70*F day and an 90*F day. There is a remarkable difference. So if 20*F has an impact, imagine the difference between outside temp and underhood temp. Let me give you some #'s. I just took a test drive with my Bravada. The intake duct work was 127*F on the outside (measured via infrared thermometer) with an ambient air temperature of 76*F. HUGE difference and would make for a very noticeable performance difference s/c or n/a.

Ya know you could always try a Tornado Fuel saver. I know a lot of people say that they don't work but I installed one and actually had some decent luck with it. It did increase mileage a little bit 1-2 mpg. And my blazer does feel a little more powerful now. Plus it added a little bit of a bubbling noise to the exhaust (sounds pretty nice) The only thing I would worry about is making sure that your after market intake has the same size piping as stock or it won't fit in that one. But hey for $70 you actually get some pretty decent results.
