Although the fins might help, there is more to it than that.
the idea behind the Bluebomber mod is to replace an after market Intake
's MAF housing with that of the stock air box, this was done because:
Celica's MAF and ECU are calibrated to detect and calculate air flow thru a 2.5 inch opening with fins just in front of the MAF to minimize air turbulence (stock air box). Notice the fins are straight and not angled in any way. This is done to ensure that the air passes through the reeds of the actual maf sensor at a straight angle with a minimum of turbulence.
Most aftermarket Intakes
, K&N etc etc.) place the MAF in a 2.75 inch finless tube environment; this can sometimes throw off the readings the MAF sends to the ECU, which can sometimes lead to the ECU miscalculating how much fuel to inject into the cylinder and cause Bogging or a Check Engine Light to come on because the mixture is too lean or too rich.
NOT, repeat, not everyone who uses an AEM
or Injen Intake
will get CELs or bogging.
The TPR CAI and intakes with the BlueBomber MOD dont Bog and throw CELs because they have the correct MAF environment dimensions and fins to minimize turbulence near the MAF, which helps to ensure the ECU always gets the correct air flow reading from the MAF.
