Hey guys so i was just getting ready to install my perrin intake and i took everything apart but before installing it i looked in the part that holds the maf that whole section of the intake Is gunked up with i guess oil? does anyone have a way i can clean this out before i install it or should i just let it go?

Just buy any maf bottle cleaner at a parts store

 

Excellent cleaner! I use it every 30K and have great results. Well worth the money.

 

just bought the crc um only thing is the gunk isnt going away it on the outter ridge not the inside were the little red thing is. the outter ridge has like a half an inch of build up...

 

So glad I read this thread! I went out and cleaned my sensor after reading, and now finally after months and months and pulling hair out, my car hits 11:1 afr at red line, and not around 12.5~13.5:1 (yes you read that right).

A huge sigh of relief. It wasn't even that dirty - nowhere near as bad as the photo's in this and the linked thread!

 

good god i think thats the worst maf i have ever seen. i recently cleaned my maf and it had never been cleaned before with 100k miles on the car and it was no where near that bad. i hoestly dont see how that much gunk got in there.

 

Holycrap!

 

Damn that's bad. Were you running the stock intake box before the Perrin?

 

that picture is after like 20 min of spraying my maf lol. only half the gunk is in that picture... but no before the install it was the stock intake with a cone on it not the box. the cone was rusted to hell tho....

after install of my perrin my tune got all messed up. my AFRs at WOT went from 10.9-11.2 to 11.8-12.5.... and i cant get retuned cause i need a clutch lol

 

Dude its cause that filter is mega crappy....looks like oil, salt,dirt, small animals made it thru that so called filter. Ok now spray the maf again douch that thing and carefully use a old toothbrush an scrub.....dont hit the little diode thing in the main intake track box area. Repeat until clean...maybe use some lightly compressed air also.

Ps...the perrin filter will come soaked with oil...so you may have to do the maf cleaning soon again so it dont get as bad as it is now.

Give her hell!

 

Jesus, your maf looks terrible, I don't think I've seen one that bad before! CRC is the stuff you should be using. After you spray the CRC stuff in there try wiping out that crap with a paper towel, BUT make sure to not damage the honey comb or touch the little orange sensor in the middle.

 

I type slower than you I guess, haha. Yeah, the Perrin filter comes pretty oily...I wiped my perrin filter with a couple paper towels to try and soak up as much of the oil as possible before I installed it.

 

Yeah i ended up using the entire can of crc its all clean now but i didnt soak up any oil off the perrin i figured it was supposed to be like that.... plus it took alot of forcing to get the intake in lol ill clean the maf when i change the oil in the next few weeks... anyone able to tell me y my maf got so bad?

 

Just did mine, some dirt not to bad and I run an HKS filter.
