Air Intake, Any suggestions Options

[aveale]

While poking around E-Bay between patients, I noticed a listing for an Cold-Air Intake for the D-Jet.

I have used them in my other car with noticeable improvement in engine pickup.

Anyone have any 914 success with these lately?

Have not used one before, however. The 914 unlike a "conventional car" probably needs one less. The intake is in the engine bay, which is flooded with cool air, as all air flow for engine cooling is top down. (assuming all your rubber engine seals are in place) So the air intake is already in front of the enigne, not behind it. It is already getting cool air above teh motor in the air stream. In a conventional car, the stock intake is often above the engine also, but trapped under a solid hood, and sucking hot air since it is behind the radiator, cacthing hot air from the air flow.
The cool air systems on a conventional car simply move the intake to infront of the radiator. In the 914, the stock design is essentailly that. True it is a bit cooler outside the engine bay, however the improvement you would gain might not be noticable like it would on other cars. (and who wants a hole in the engine lid for an external from engine bay filter unless you have a track car)

There are higher flow filters, however if you are still running a stock injection system, keep the filter stock. If you get rid of the stock filter, you loose hoses that provide crankcase breathing, and gas evaporative control both of which are good things to have. You will have a cleaner engine, less oil leaks, and be less polluting. m For many with a stock engine, the stock filter works fine, the factory didn't design an overly restrictive system.

Aftermarket filters can make your car seem faster, as they usually change the noise a bit louder, hence you think you go faster. You can do the same thing with a noiser muffler, without the problems with breather and evap hoses.

If you have an early 914 with the oil bath filter, you can upgrade to the stock later paper filters, which many folks like better, maintainance is easier, and in hard corners, the oil has sloshed out. I do not mind them too much, but heck I grew up on old VW's with the same oil baths, framiluarity breeds foundness I guess????

if you have upgraded to carbs, and require greater than stock air flow, there are many brands, with K and N being popular (I have one on a Buick powered 914) too choose from. As with the Stock FI, on carbs you still need to provide for crank case breaters to the filter, and it is nice for the air to hook up the stock gas evap system it does not cost ANY horsepower or effect drivability at all, and gas fumes from the tank are a BIG contributor to the smog from a car, even when parked. Most carb filter kits leave it up to you to figure on how to connect the hoses, (ie you need to make the fittings, they ain't there) but that does not mean it should be overlooked.

I personnally with a stock engine, would leave it stock, avoid oil leaks, keep emmisions low, and the noise lower, Intake noise is annoying to me, but I for some reason sure love the sound of a Bursch exhaust.

good luck
