This package includes a set of ISR long tube headers with a pair of our plug and play o2 extensions.You will NOT find a better deal anywhere else!!!
The ISR long tube headers are constructed with 304 brushed stainless steel and heavy duty flanges. Designed with a stepped primary, these headers are built to retain as much low and mid range torque as possible while allowing for good top end horsepower gains as well. Meanwhile, The innovative High Ground Clearance, "HGC" design places the collector in a position to maximize ground clearance without sacrificing performance.
Each header features 2 o2 bungs placed downstream of the collector so that you can utilize your factory upstream and downstream o2 sensors. Our plug and play extensions for the upstream o2 sensors make this process seamless!!!
Which "Type" of o2 extension do you need?
There are four different types of connectors used by Nissan throughout the different models and years. The most accurate method of determining which type is needed, is to compare the connector on your vehicle with the different types offered. Use the reference guide and pictures provided. Included:
