The OE Match Cylinder Heat Shield Kit for Porsche 996 3.6L (2002 onwards) provides a complete solution for replacing worn or corroded ignition heat shields, ensuring proper protection of coil packs and surrounding engine components.
This kit includes two OE Match 99610444502 heat shields, designed to fit both left and right cylinder banks. These shields are mounted over the ignition coil packs and act as a barrier against radiant engine heat, helping maintain stable ignition performance and preventing premature failure of sensitive components.
To ensure correct installation, the kit also includes four genuine Porsche hexagon-head bolts (90037816301, M6 x 16). These bolts provide secure mounting and proper clamping force, essential in high-temperature engine environments.
Heat shields in this area are exposed to extreme heat cycles and moisture, often leading to corrosion or deterioration over time. Replacing them as a pair, along with fresh hardware, ensures consistent protection across both cylinder banks and avoids issues caused by weakened or seized fasteners.
This OE Match kit is ideal for maintenance, ignition system servicing, or preventative replacement on higher mileage vehicles.
Original heat shields commonly corrode, weaken, or fail due to constant exposure to heat and moisture. A damaged or missing shield can lead to overheating of ignition coils, increasing the risk of misfires and reduced engine reliability. Replacing both shields together, along with new mounting bolts, ensures proper thermal protection and prevents issues caused by worn or seized hardware.
When to replace:
• Visible rust, corrosion, or deterioration
• Missing or loose heat shields
• Ignition coil issues related to heat exposure
• During coil pack replacement or servicing
• Preventative maintenance on high-mileage engines

Engine 3.8L, 102.00mm Bore, Ductile Iron flanged liners (With Hole and cutouts machined)
Fits:
Porsche 991 3.8L MA1 Engine Only Price SET OF 6
Porsche 997.2 3.8L MA1 Engine Only Price SET OF 6
NEW Ductile Iron cylinder liners suitable for repairing damaged Alusil bores in 991 engines.
These New Ductile liners now have the cutouts and gudgeon pin hole already pre machined into the liners. The liners will only need to be bored and honed after fitment.
These liners are becoming very popular, with increasing numbers of cars suffering from scoring in the bores.
The liners will need to be fitted by a professional machine shop. You will not need to get special pistons or rings, as the original spec ones can be used with these Ductile liners.
Fitting guidance:
Interference for the liners
into the block is 0.038mm +0.0127 / -0.000.
The liners need to be
cooled/frozen and the block heated.
Make sure that the bored
finish on the block is very good, maybe honed before fitting the liners.
After the liners have been
fitted and the temperature equalised, press the liners down to make sure they
are seated on the flange.
Bore and hone the liners to
the correct piston size, then press the liners again to make sure that they
have not lifted a small amount (This can happen).
Now face the block completely flat.
