Default Bosch Fusion IR 4514 for PT Turbo

Hi,

did any of you try that spark plug on his HO Turbo?

Sparkplugs.com - Application Search Results

I made good experiences on spark plugs with 4 mass electrodes in non aspirated engines. Smoother idling, quicker throttle response.

Bosch is recommending this 4514 only for the n/a 2.4 engine, but you can use almost every spark plug for both engines, and gapping should not be a problem with these plugs

Any volunteers?

Georg

No volunteer here. Since the PT turbo and Neon SRT-4 came out we have been told to stay away from platinum plugs in a turbo engine. The turbo engine runs hotter than a non aspirated one and platinum plugs have been known to melt. There's a good reason Bosch doesn't recommend platinum plugs for turbo engines. I do use Bosch platinum plugs in my wife's '04 non turbo PT and they work great. Besides, I've been using the stock Copper Plus plugs in both my modified '03 GT and my highly modified '05 Neon SRT-4 with great results.

Hi Mean Green,

I know about the issues with Platinum plugs in the mentioned engines. I use NGK LZTR4A-11 (Copper) on my Gt. They work fine, but my interest in these Bosch plugs is not caused by the electrode material, but by the 4 mass electrodes. Unfortunately there is no spark plug with 4 mass electrodes and copper center electrode available that fits to the 2.4 Chrysler engine.

At least the Bosch plug has obviously a part of Iridium in its center electrode.
