    Default AE86 Header welded on fittings

    Car - AE86

    motor - 4age

    use - happiness

    problem - question not a problem

    occurs/started when - when I look at the pictures

    personal situation (if applicable)- I've been looking at the pics of headers from the USA and i'm wondering what the fittings on top of the headers are for? big hole on rear most pipe from block and the four other weld ons...what are they all for?

    possibly individual lambda sensors for each cylinder?

    Oxygen sensor in the big hole, and the others look like they're for the standard heat shield.

    nah the O2 sensor is on the second pipe
    I'm talking about the pipe coming straight from the fourth cylinder
