Advice about non turbo headers and intake

Recommended Posts

Hi I bought an 05 is300,  I have a nice note out of the cat back I installed.  But I would like to buy these 5 to 1 headers from the US for 170 AUD. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F332738594033

From videos I've watched, the heat generated can melt your stock intake,  possibly melt the fuel rail directly above them and possible cause a carpet fire if I don't try and repurpos some bits of shielding.  Any advIce would be much appreciated.

And yes I will be getting a retune after the header install

if you buy any us made headers you will have to slightly modify the area where the steering colum sits and relocate the O2 area as it hits the sterring knuckle
