Bolney then...John will probably make an effort too as there should be a nice collection of R32's on display
IMO the reason I had to rebuild my 32K mile old R33 GTR engine prior to sale was the HKS "filters" didn't! The text book signs of poor filtration were all there, eroded compressor blades on both turbos, excess bore, piston and ring wear, and excess valve guide wear. i just CANNOT undersatnd what peoples obsession is with removing the stock air box. Nissan designed it well, it's no real restriction, it's quiet and pulls cool air from outside the engine bay and the stock pleated paper element is a superb filter.Scott said:John,
I wasn't saying you were quibbling over money,
just all the engineering, durability and testing work
has been done for you by HKS/Apexi/K&N.
I'd also be concerned about fibres being sucked out
of that filter material and being injested.
I'd play safe after all its a very expensive engine.
