How much of an improvement did you notice over stock and what type of improvement? The SLP runners are siamesed aren't they, I've read that siamesed runners do improve airflow but reduce low-speed torque, is this correct? Is any port matching required or are they a direct fit to stock dimensions??

 

They are "Semi-siamesed" In otherwords just about the first 2" is cut out.

 

I have the slp runners. I think i lost a little low end in the gain of some top end. I think that if you dont port your intake plenum that your not quite taking full advantage of the siamese idea behind the runners. I just did a custom jobby with a dremmel and some air tools Ive heard that you might not notice a real difference until you get rid of the peanut cam.

 

are you guys still using the stock manifold??

 

hey, i ported out my plenum totally and did some of my own work on the runners to better siamese them. i didnt really notice any loss in low end, but up top past 3000 i noticed a nice improvement, pulls harder as he rpms go up. def. worth the money.

 

are there any faq's or site detailing this mod. my friends 91z tpi/m5 has an intake leak and it is time to tear all that off. so i figured we'd do some mods in that area.

Worth the money if you do other intake and exhuast mods
