yea ive gone threw 3 mafs in the past 4 years and i think its due to my injen intake ..... it always gets wet and ive done everything to try and seal that area off from water.

Im thinking about switching up to a 3 in from zzp or ottp cuz they seem to be angled much better.

 

I keep hearing all this bad crap about Injen intakes, which is what I was planning on getting next week, but I think I might go ZZP instead, especially if they're causing this much trouble with the rain. And considering how much it rains up here, like the storm we got last night, Rice, I'm not sure I want to take the chance.

 

ill sell u my injen at a discounted rate lmao

 

lol. I think I'll pass. :P

 

I ran an Injen intake, and had no issues at all in terms of water / wet filters.

Weird.

 

I have a K&N oiled with hydro shield with the plastic under the intake area ripped out. No issues in the rain. Maybe just how the Injen sits.

I kinda wanna go ZZP since it sits higher, but wasting all this money on intakes is just dumb. I still have my stocker that I'm debating on modding like how Staged has his,

 

man i got my maf sensor sealed with silicone, i have rigged up a system in the headlight bracket to stop rain dripping from the top. i really dont think it matters what intake you have. the problem is where the filter is located. i know sylver has no issues, but he uses a brand new filter every oil change and a wet sock every 2nd or 3rd oil change lol. my other car's intake wasnt a injen and yet it was way worse then this car.

i can tell you tho, this new car is so sensitive to rain that soon as it lightly rains it acts up. my maf is brand new and i usually run a sock. i have no leaks in my intake at all. so im stumped.

 

ive also tried isolating that area from water by taping everything, trying to keep the drip from happening. idk anymore lol. guess i'll just have to turboswap it to get rid of the problem entirely :

 

Do it

 

I change my air filter every spring/fall. I do alot of gravel driving in the summer as my family and friends live back home on farms. I don't use a hydro filter or a pre-filter either. I have a jet maf sensor if that makes a difference

 

how does staged have his stock one?

 

Ask and you shall receive....



I modified my box this way so I would be able to run the OEM replacement K&N E-0777 filter. The K&N filter installs the same as the OEM filter, so you need the bottom of the box to hold it on. The amount of holes, and size of the holes I drilled is about the equivalent of leaving the bottom of the box off. Whine is nice and loud, the filter is still protected, and you have nice composite material (rubber and plastic vs. aluminum) keeping the intake air charge insulated from the heat.

Not to mention I flowed a good deal more air with this setup vs. my old injen intake.

35.03 lbs/min modified airbox

33.95 lbs/min injen

 

ohhh ok. I just have the lid off with a come filter and hydroshield.

 

That works to

 

My SC used to do this all time. It was the worst with the AEM dry flow.

The amount of water that makes it into the fender well is brutal. My inner fender well was installed incorrectly too. Ensure all that is tightened and that there is no moisture getting in between the maf and the inlet. I worked on a buddies where this was the case with his Injen.

I actually added some fasteners to help the fender well stay more secure as well as wrapped the MAF in a balloon etc to protect it from splashing. It can get a lot of water on it. Sounds like you are doing a fair amount of protection too though. Weird.

The Hydroshield in my experience doesn't resolve this issue 100% but it does help. However I have seen a few where it traps dirt and debris too...

Tip: If you shift under 2.5K RPM it wont buck and bog and all that ****. So when its super wet out just shift at low rpms and you should be all good.

 

Correct.

A hydroshield is water repellant, not water proof.

Dryflow filters blow.

 

Staged that's a very good idea I never thought of those points about the plastic and rubber vs aluminum. Would you say you flowed better due to the factory piping and the holes? Or just due to poor Injen sized piping or what? I also have an Injen so if I can keep sound protect it better and flow better I'm going to modify my old stock airbox and "revert" lol how did you measure flow if you don't mind explaining just so I know if I also am flowing better after switching or not lol

 

hes just going off of what the maf tells him on an interceptor or hptuners.

was that comparison done on the same day at the same temps? and did you dial in your maf with the injen?

i have been through some serious floods with my stock airbox. its the reason i dont go to an aftermarket intake, because it rains so much here in alabama.

 

yeah I dont drive hard in the rain at all. if I even go out in it. just to avoid the situation altogether.

 

Test performed same day, same exact temps, all within an hour of each other (time to remove and install intakes).

I ran the test multiple times just to varify.

Also to note, the stock intake is larger than the Injen. I have the exact measurements of each somewhere. The stock intake is a full 3" at the MAF housing. The Injen is under 3" there, and only 2.75" at the inlet. Injen does this to prevent setting lean codes. Neat idea for un tuned cars, but in reality, it restricts flow a bit.

The stock intake was designed very well for our cars. Back in the day when the aftermarket intakes came out, the louder whine produced by them made everyone think they gained this huge amount of power. Very deceiving. All you need to make the stock intake flow a bit better is a high flow filter, and some more air entering the box. Neat.

To log how much your car is flowing select MAF lbs/min on an interceptor gauge or HPT, and log it vs. RPM.

 

glad to know that im not missing a whole lot.

i just have the plain jane airbox, and it whines decently with a 2.8" pulley

 

thats fairly ingenious. i have often thought of using a combination of stock and generic polished tubing to create my own intake. the stock rubber tubing is rather ugly if you ask me. hahahaahaha the use of the filter box would help alot with the water and debris.

 

I had this before. Infact, Cobalt Addiction sold it. It was called the XTC intake.



^ I hacked the **** out of this airbox. Yuck

I like the stock intake plumbing. I jazed it up with a K&N decal, lol.

 

Dude everything on your car looks showroom... Not saying mine isn't clean, but look at that trans! No corrosion or dirt at all. Impressive
