If you're looking to enhance your 1991-1995 Acura Legend V6-3.2L, the Injen IS1401P is a solid choice. This short ram air intake system has been thoughtfully designed and rigorously tested to deliver a noticeable boost in performance. Many users have reported an increase in horsepower that makes their driving experience much more enjoyable.
One of the standout features of the IS1401P is its mandrel-bent aluminum air intake tube. This design allows for a smooth and efficient airflow, which is crucial for optimizing engine performance. Customers appreciate how this intake not only improves power but also maintains safe air-fuel (A/F) ratios throughout the powerband, meaning you won’t have to worry about additional tuning.
The kit comes equipped with an Injen SuperNano-Web dry air filter. This filter has a larger surface area compared to standard filters, which enhances airflow while ensuring top-notch filtration. Users have noted that the intake system produces an aggressive engine tone when you really push the pedal down, adding a bit of excitement to your drive.
For those who like to personalize their vehicles, the IS1401P is available in both a polished finish and a sleek powder-coated laser black. Installation is straightforward, as it's a direct fit for the specified Acura models, although it does exclude non-TCS equipped vehicles.
Here’s what some customers have had to say:
"The sound this intake produces is fantastic! I can really feel the difference in power, especially on the highway." - Mike T.
"Installation was a breeze, and it looks great under the hood. Highly recommend for anyone with a Legend!" - Sarah L.
