Bought replacement MAF from O'Reillys for $300 (that's before the core credit) but am going to return since I see them cheaper everywhere else. Even the dealership was around $200.

I'm looking at ECS Tuning - http://www.ecstuning.com/Audi-B5_A4-...Engine/Intake/

I see three for my engine (1.8T AWM) from $109.95 - $184.70. Any reason I shouldn't go with the cheapest? I understand that typically you get what you pay for but am not finding any reason why not. Or are there any other sensors that are highly recommended? The car is stock with no plans for changing that anytime soon.

Brand New - $109.95

Brand New - $144.95

just get the cheapest, bosch makes quality products and there should be no difference at all.

 

got mine off of ecs lol

 

if your awm, just run mafless

 

You can do that?

 

Absolutely. Any a4 with a MAP sensor will run mafless, because the ECU will fall back to using the map. I ran this all summer with a cone filter. Upside is you can vent the DV, and not have misfires (yeah it was ricey, but with an open downpipe, it was damn amusing, everyone thought I had the baddest sleeper)

 

I had Advanced Auto price match the Bosch from ECS works fine on mine but i'm AEB

 

Will that cause a CEL or limp mode though?

 

Ture this is what I'm doing right now too lol.

To CCA4: No the ECU is constantly monitoring and changing the A/F ratios even at WOT, so it technically doesn't "need" the MAF

Really? I have never heard this. Or venting your DV ever for that matter.

 

It did throw a CEL the first time, but after that I havent had an issue. Ill unplug it after class, and drive around to see what happens
