That's a really small difference, really small. Although, my AFRs are more 11.2-11.4 under throttle. It's a different engine. I don't know what the targets are for this motor. But .05 difference is very small.So before I switched to an AEM drop in filter I decided to see what the air fuel ratio was with the stock filter. Saw a low of 10.34 stock and 10.29 with AEM. Wondering if thats why people are seeing bad gas mileage.
Stock mass air flow was 227g's. Aem mass air flow 231g's
Its a only been like 2 days so its hard for me say. I would go with AEM because its a dry filter rather than the K&N oil. The stock filter looks very cheap honestly and id rather just leave me AEM in no matter what. I do agree removing that net might be beneficialDo you recommend the AEM drop in or a K&N drop in or leave the stock air filter. As from the looks of it the AEM drop in is getting more air to the turbo from the readings off of the MAF sensor and I am sure it would get more air if the netting was not there in the air box.
