This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.

E36 M3 OBD-I Stage 1.5 Performance Package
Peak Power Gain: +32hp / +23ft-lbs
Rev limit: 7000
Octane: 91 or higher

This Stage 1.5 Package adds the option of larger 21.5lb fuel injectors to the Stage 1 Euro HFM kit. The 21.5lb injectors (23lb at BMW's 3.5 bar) were standard on the S52 3.2-liter engines. Because that engine has found its way into many other E36s, we put this kit together to use the Euro HFM, intake, and the stock 3.2 injectors. Also, it's been necessary for some people to add more fuel to account for cleaner-burning gasoline used in the US. With the lower grade fuel, pinging, knocking, or lean conditions may be experienced with the stock 3.0 injectors. The issues people are having seem to be geography-related (California, the Northeast, etc.) but many people feel safer having a fuel 'safety net' and this Package meets their goals. We also offer a Stage 2 Package with 24lb injectors if these are still not flowing enough fuel. There is no performance gain with only adding the 21.5lb injectors.

We use the aFe 'Euro' Intake Kit, Bosch Euro HFM, Bosch 21.5lb injectors, and a special TMS Stage 1.5 Performance Chip. The aFe intake is made with heat-blocking materials, reducing underhood emperatures and not contributing to heat soak of the air filter. The aFE intake uses an oiled cotton air filter for maximum air flow and excellent filtration.

With the undersized stock air sensor, the M3 is gasping for breath. But with the larger 3.5� Euro HFM and Euro Intake, the M3�s engine can breathe a lot better. This kit works on all 1995-1999 M3s with the US S50 3.0-liter or S52 3.2-liter engine (and using OBD-I engine computer).Our TMS Performance Chip is tuned specifically for the Euro HFM, aFe Intake, and 21.5lb injectors. Our chips require premium fuel (91 or higher) and allow us to alter the settings on the engine management.

Related Upgrades: We are often asked what would complement our software and intake packages. Within any Stage, we recommend our Underdrive Power Pulley Kits and a cat-back exhaust. The Power Pulley Kit will under-drive the alternator, water pump, and power steering pump. Under-driving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10 horsepower at the wheels.

We also recommend upgrading the cat-back muffler for slightly more performance, lighter weight, and a more-aggressive sound. Our favorite E36 M3 mufflers are the Supersprint, Borla, or Corsa exhausts. The Supersprint is the quietest and most like stock while the Corsa is the most aggressive (Borla being in the middle). You can expect a gain of 5whp with any of these exhausts.

Clickhere for feedback on this package.

E36 M3 Stage 1.5 Engine Upgrade Kit includes:
aFe 'Euro' Cold Air Intake (filter, heat shield, intake tube)
Bosch Euro M3 HFM
HFM adapter
TMS Performance Chip (we need your car's production date, choose from below)

21.5lb Fuel Injectors
This kit is sold without the fuel injectors but we can sell you a new set. Select the option below if you would like new Bosch injectors sent with your order. Otherwise, all M52 2.8 and S52 3.2 liter engines came with them so there are lots of used injectors available from eBay, forums, Craigslist, etc.

Applications:
1995 E36 M3 3.0 (21.5lb injectors required) (manual transmission only)
1996-99 E36 M3 3.2 (manual transmission only) only for cars with OBD1 conversion
any S50 or S52 with OBD-1 in an E36 (330i, 332i, 332ti, etc)
