Exhaust Heat shields

Hi everybody. Long time lurker first time post. Had the car for 5 years- love it. Red spyder type.

So Iíve corrected the valve guides and decided to remove and replace the headers before problems occur. I found a pair of custom SS headers and had zircotec spray them performance white before they came back to USA from Europe. The car is in for a major and decided to swaintech white lightning the cats and x pipe. Will be applying 2000 degree hi temp rustoleum matte black to keep cosmetics.

My question to you 355 owners... I can not find if there are oem heat shields to protect the radiator and oil lines. I have found carbon fiber aftermarket and if no oem shields then I would first apply zircoflex3 on them and have them installed.

As this is an experiment with performance, and since zircotec reoprts a Ferrari 360 race team reports a 50c reduction in underbonnet temps post treatment, I plan on reporting operating temps back here at a later date.

So, can somebody confirm if there are oem heat shields that protect the alternator and oil lines separate from the header exhaust shrouds?

Very interesting experiment and I'm doing something similar with the 550's V12 engine, but did not use Zircotec.

Regarding heat shields, for the 550 engine, we do have one that protects the starter, but not the alternator. Fuel lines are insulated, but the fuel rails themselves are not, nor is the intake manifold and I've often thought those components could be candidates for Zircotec, or something similar.

Please keep us updated!

High mileage, low compression, and missing on a few cylinders.....just like my cars.
