Don't want too upset those who sell this item
Thats my opinion, said without malice, just an honest appraisal of what I feel about the spacer. No more no less. If it affects your sales, sorry
I was under the impression that freedom of speech was available to forum members
My argument is this:
Nissan R&D would have done countless tests to find the optimal air circulation around the plenum, agreed?
So,
Who designed and verified the spacer was an "added" benefit to the air circulation, I would be very interested in seeing the document.
I don't worry about the hp gains/losses, show me the actual air flow charts and extra cubic capacity of air that the spacer provides, and how it affects the air
flow to the front 2 cylinders for their benefit.
When I fitted mine, TBH I didn't have that WOW factor I thought I was going to have after reading the hype surrounding them. So for me I was a tad disillusioned by it.
If I thought it was great, then I would praise it to the hilt, But I don't, Sorry
