just wondering if there is a difference between the s4 TII and the s5 TII intake manifold gaskets, im looking to buy the 2 gaskets from ebay but it says 89-91 and i have an 87, also my gasket has an extra little hole in it that the one on ebay doesnt have. can sumone help?

 

heres a pic of my gasket and of the ebay gaskets, so u can see the difference

 

looks like there is not a passage under the outer ports but those I believe are just emission passages.

 

there is a difference in the upper gasket but not the one that bolts the lower manifold to the engine block

 

They are both different.

Mazdatrix has pictures of the different gaskets if that helps:

ok and another question is. Do these gaskets actually have a power gain like they claim to have or is it all just talk to get u to buy them? cuz $40 for 2 gaskets is pretty expensive to me considering u can get them for half the price from mazda trix. heres the link

Do they offer proof?
Then they are full of ****...which they are.
