AC Premium Bosch Logo H4 Headlights

There's a big demand for the original Bosch H4's and we restore a lot of them but they are getting more difficult to find. Bosch is no longer building them - the current ones sold by Porsche are built by AL (Automotive Lighting) in Czechoslovakia and the lenses are marked "AL" instead of "Bosch". Those are fine but we decided we could do a little better and get a little closer to the original Bosch's with a few significant improvements.

Best-in-Class® AC F-Series & G-Series Taillight Assemblies - Complete

Restored Originals or High Quality Reproductions?

It hurts a little bit to say this. But after 25 years of restoring original parts it's become apparent that, unless you absolutely need originality, much better price performance is delivered by new Best-in-Class reproduction parts. So my job shifts from restoring parts to finding Best-in-Class parts (restorations are more fun though!).

Perfect Example

These new reproduction housings are a perfect example. They are all metal and the details, craftsmanship and fit are excellent, on a par with the originals. They are relatively inexpensive and 100% complete plug n' play ready to install (which is where the great deal comes in).

The 5-rivet TTG driving lights have always been a favorite of mine (who knows why - kind of like the affection I have for the side oil filler on the 72's).

45% Brighter Incandescent Turn Signal & Taillight Bulb Kit

These bulbs were originally used by a Japanese auto manufacturer in their high-end cars. They evidently made the decision that they were to expensive and went back to basic bulbs.

These are 45% brighter and have nickel bases to prevent corrosion. They are the best way we know of to significantly increase the brightness of your signal light bulbs short of installing LED's. And they do retain an original look. They're expensive though. Your call (we sell a lot of them).

JA: We spent many hours researching first what would be ideal to include and this kit and second the best value specific items to include. We were disappointed when we introduced it as it was a complete dud. We're featured it in this section because there's been a big upsurge in interest of late.

This kit is designed to fit perfectly into your smugglers box where it can be stored out of the way. Yet it contains everything you need in one kit to take care of many common roadside problems. It's designed for the self-reliant Porsche 911/912/930 owner who would rather get rolling on their own without waiting on - and depending on - AAA. I guess I'm old school but it's nice to be self-sufficient.

DME Solid State Fuel Pump Relay for Porsche Carrera 3.2, 964 and

The original mechanical DME relay is a common point of failure in our cars. These are solid state making them far more reliable. Made by a one man shop, an electrical engineer, quality is Best-in-Class. Plus the LED diagnostic lights are not only helpful, they're flat out cool.

Replace your old one with one of these, throw your old one into the glove box, and enjoy low-cost peace of mine.
