newguy... any information I can get ill take though. But I guess Id rather have true information than false. But I don't know a whole lot about cars/trucks yet. Still learning, so anything helps.

10-78 edac... What do you think I should do then?

Notice how most of these pictures show about 3 pipe diameters of straight pipe before the sensor. The sensor measures the amount of air, the computer fires the fuel injectors for the proper air fuel mixture. if the sensor is reading false air flow, the mix will be wrong. Then all kinds of trouble can happen. Maybe the next guy can pull it off your car in the junk yard. mine is stock. I'm just a heating and air conditioning guy. I am certified in air balancing of HVAC duct systems. I have seen strange air flows happen from crazy installations. All I am trying to say is a small length of full size tube would allow the air flow to run a straighter pattern across the sensor. that is why they put the honeycomb in there, to get the most accurate reading for the computer as possible. They use a clamp type fitting because a screw,rivet, or anything protruding into the air flow would cause turbulence and affect the reading. Cold air is denser then warm air. Denser air has more oxygen molecules in it so you can add more fuel, equals more power. But I think there are enough threads here that will explain that it is barely noticeable. Holding the intake higher might get you through deeper water then the stock location, but I don't know what you are trying to do with your Blazer.
If you're new to Blazers remember that they are not off road ready out of the box, and even with mods they are limited (https://blazerforum.com/forum/builds...r-45387/page8/). This was a nice build that died in a deep puddle. Keep up the good work and ask questions here anytime. SEND MORE PICTURES. Start a build thread!

 

10-78 edac... I have a 3 pipe diameter, but yes I do have a reducer connection the 3 pipe diameter to the MAF sensor. How could I connect it with out a reducer? I apologize for so many questions everyone. Like I said before, still learning everything. But the more information the better for me and the better help I could be to others.

 

Update for everybody. My blazer died today on my at a stop sign coming home from lunch. I believe it is my fuel pump that went but I also have been told it could be my DIY SRI. I will find out tomorrow what is wrong with her because I had to have it towed to the shop. I am hoping they say something about the SRI as well, to let me know if it IS or IS NOT a good thing that I have done to the blazer. If it is NOT working out then I think I am going to put back in the stock air filter box and purchase a K&N air filter for the box. Are there different air filter boxes you can purchase for a blazer? Or is the stock one and replacement stock boxes all you can get?

 

Meh, throwing a filter on the end of the intake tube won't kill an engine. You can get stock replacements that are the same as the original, or you can go with a 'real' SRI or CAI kit from specter or K&N or one of those companies. Doesn't make much difference really. I had an ebay one on mine, but mine was also a 95, and didn't have a MAF.
