The subject of closed intakes versus open intakes is popular for debate over the significance of delivering “cold” air to the engine.
APR recently introduced a new intake that fits the Mk7:
Which is better:
The open design of the intake prompted a question from a consumer about open intakes:
From this statement, it seems that APR’s position is that a ton of air is rushing through the engine compartment, so there won’t be much of a difference using the open intake.
This isn’t the only intake APR sells to consumers for the Mk7, on their website they have a closed intake that they describe the benefits of:
In the case of APR’s closed intake, the company says that Intake Air Temperatures are critical to engine performance, and they use a sealed design to prevent the ingestion of hot, under-hood air.
So what is it? Is a sealed (closed) design that keeps the engine from ingesting hot, under-hood air critical for engine performance?
Or is there a ton of air rushing through the engine compartment such that having an open intake instead of a closed one makes no difference?
Or, do you simply tell consumers whatever is convenient to sell products?
