280Z gets new lungs – K&N Filter Intake

 

 

The Datsun 280z gets a new cold air intake!

I’ve had this part for a little while rolling around in the back, thought I’d take a few minutes to see how it works.

Among all the intakes on eBay, I figured it’d be just as easy to make my own. Here’s what you’ll need:

– K&N Air Filter – various models can be used. I decided on the K&N RC-4690
– Spectre cold air intake – model #94990, 3″ 90 degree aluminum elbow
– some Windex
– Philips and flathead screwdrivers

Just a few notes before we begin, the Spectre 94990 is a 3″ diameter tube which is just larger than the original intake opening, so getting the original intake boot on the elbow is a bit tough. Hence, the Windex.

1) Use the philips screwdriver to remove the original intake from the car frame, also removing the plastic intake extension, and loosing the intake-to-AFM boot

2) Attach the K&N filter to the elbow, tighten

3) Fit the elbow to the intake-to-AFM boot (you can use some Windex here to help it slide on). It’ll be a pretty tight fit, but it’ll go on. You can also use the flathead screw driver to help get that last bit of lip over the intake tube.

Estimated completion time: 30min – 1hr

All the parts laid out…

Dry fitting the K&N intake to the Spectre elbow – a 3″ ID (inner diameter) filter SHOULD fit on a 3″ OD (outer diameter) intake.. right?
