I am in agreement with Eric on the helix spacer. I bought this
1 inch "SPACER" (and thats all it is) from Street and Performance
electronics, 5 miles down the road. The HELIX does nothing. They
were never able to furnish me with dyno proof of 14-18hp. However,
the spacer does seem to provide some performance. Just guessing.
I say this only because as with any spacer,it adds to the plenum area
and possibly helps the airflow make the TB to intake transistion. I
would prefer one like Eric's, without the helix in it. Not worth a
100 bones by any means.
