Wrapping stock intake with tinfoil bubble and then heat resistant wrap?

Just looking to avoid heat soaking and get colder intake before the engine itself recirculates it through the EGR as hotter air. Could also use a dynamic air scoop and boxed off heat shield but can’t find anything online. Not tryin to install an injen style cold air intake, just looking to modify the current stock one with add ons and wrap ons.

Any objections?

 

To reduce heat soaking and bring down engine temps faster after a redline.

 

Yes that’s the idea, small benefit, no harm. Mostly for reducing heat soak especially after redlining. I don’t want my engine coolant sitting at 190 degrees in idle after I redline from the last stop light on non-highway driving.

 

How soon is soon when we are sitting at 75k miles total right now?

I’m pretty positive anti-heat soaking measures will prolong that inevitability.

 

Redlining as in going into higher RPMs (the red part of the RPM spectrum for each gear)


If my water coolant reads 190 degrees at a stop light because I redlined from the last stop light then the engine temperature and coolant is going to exceed 190 degrees once I redline again when the light turns green. I would rather have it sit at 188-184 degrees on average after each redline to the next traffic light especially during summer temperatures and conditions.

 

Anything higher than 2200 RPM in city driving gears is redline, any acceleration that reaches the “PWR” band is redlining. Anything over 3500 RPM is absolutely redlining on highway speeds.

The main purpose of this wrapping material is to prevent heat soaking during idle, like if the coolant reads 190 at the stop light with the engine off, not running, then accelerating again into +2200 RPM once the light turns green you will start seeing coolant temps into 195 degrees just from that situation during hot summer days because it sat at 190 at the stop light without any way or where to exhaust that engine bay heat. I’d rather the car be at 184-188 degrees before arriving at a stop light from anti-heat soaking measures. I’m not just wrapping the intake tube, I can apply the thermal radiation retardant material anywhere on the intake housing that’s near the engine bay to prevent radiating engine heat transferring to the intake too quickly.

 

I’m not looking for performance boost, the stock intake has its own air restrictions minus the bell mouth on the intake tube. I’m looking to retard thermal radiation transfer to the intake housing from the engine heat.

 

I already use the cabin air to exhaust engine bay heat by leaving the settings to “HI”, no AC on, no recirculating mode on and have them set to feet and windshield before pressing the off button. The engine bay reaches temps around 200 during redline if you have all those setting to on or “LO” (coldest settings) especially if you have recirculate ON, the engine bay heat has no where to exhaust through. In combination with this I plan to wrap the intake housing with material that reduces thermal energy radiation to the intake parts.

 

it’s literally 50 bucks, some cutting with scissors and some tape to make nice long sleeves for the intake housing where long sleeves can be applied to the intake housing especially the tube, I heard literally wrapping it like it’s grip tape is the worse way to do it. You want an air gap between the wrap material and the intake housing to create an insulating effect.
