When reinstalling you should remove the rubber end cap from the throttle body to intercooler coupler. Remove it from both sides if possible. These pop off and cause leaks eventually. The sooner you can remove them the better. It also makes install much easier.

"these pop off and cause leaks" but you're saying we should remove them first? So what's the difference between us removing them or them popping off on their own...they're gone either way, right?? Can you clarify for me, and whomever else here is not as experienced with these cars as you are? Thanks! |

Its the rubber end pieces around the ends of the throttle body to tmic hose. Its the one closest to the driver side fender. It is prone to causing a boost leak. If you have a bad enough boost leak it will sound similar to an intake on your car. Pressurized air leaks out and lowers the psi levels going to your engine.

No, it isn't prone to causing boost leak, it's prone to causing the entire coupler to blow off the throttle body. I suppose that could be considered a massive boost leak, but you get my point.

im not sure what they are talking about^^ (dont understand)... but i used just a little touch of silicon grease and the tmic slips on and off no issues.
i figure if it pops one of the hoses off... ill just clean it off and put it back on. no issues so far and it flop on and off with ease. (and yes, dont use oil on silicon) |

sorry does anyone have a picture of this hose that pops off? I'm looking around the engine bay and i'm not sure what i'm looking for.

HeroCrank I would like to see some thermal images of a properly shielded TMIC vs a FMIC.
I have a hunch that the FMIC might get more heat soaked due to its proximity to the radiator. I need data though and you are the man with the nice camera. |

Its very hard for me to get people to let me infrared their cars without paying them or giving them something. Hell I can't seem to find anyone to let me infrared their OEM heat shield set up for comparison up here. But all things aside, I am totally game for that, just arrange something with someone with a fmic. A manufacturer that is willing to participate in a heat soak study, that will donate the product maybe?? I personally do not know anyone in the state with a fmic that will be willing to help out.

I have a question that may or may not have been answered before. Bought PTP turbo blanket & Wrap for DP. My DP is catted Invidia. Is it OK/good to wrap the catalytic converter? Seems it would help it to function more efficiently. Does it?

This could cause lots of problems... CELs, damaged sensors, fires, etc. Just wrap ahead of the cat.

I'm not wrapping sensors. The cat in the Invidia DP is a high-flowing 'racing' type, not the stock ones. Ebranch, do you have experience with this or someone you know? Thanks. |

No first hand experience... I've only wrapped headers before, but I worked for Bosch for 5 years. The cat is meant to dissipate heat; wrapping will retain this heat and elevate inside temps which would push your o2 sensor out of its operating range. This wouldn't happen in, say, a 10 minute commute, but hot summer days or tracking would pose a threat to your sensor. In EXTREME situations, this could cause a fire although unlikely.
I don't see any benefit to be gained from wrapping the catalytic converter.... Just my opinion. |

Sounds logical. Thanks for the detailed answer.

Thanks for your responses.
As I understand it, automotive manufacturers, in the interest of lowering emissions, want the catalytic converter to reach operating temperature as quickly as possible. Also, I believe they operate at something like 1400°F. It seems to me that with it wrapped with the lava wrap (not treated fiberglass), the cat would light off faster, but I just can't imagine that it could retain enough heat to melt the catalyst itself. Do you really think wrapping will push the HO2S past its operating range? Can we see infrared images of a wrapped vs unwrapped aftermarket (like Invidia) Catted DP, please? If I were close, I'd volunteer my cr for these tests. Thanks |

Thanks, HeroCrank, for your suggestion & for all these informative photos/threads. I'll definitely check out #2.
However, I was referring to testing the cat portion being wrapped vs not. |
