My stock 60mm spacer is toast. It would not come off the manifold after 197,200+miles. Can I use the FRPP 65mm EGR spacer with my 60mm Throttlebody and will it have any adverse effects this way?
That will work just fine. There may be an increase in turbulence as the air flows out of the TB and into the spacer, but you probably will not notice a power difference due to that.
