I want to buy Thermal Intake Manifold Spacer Kit and VIAS Block Plate Kit. There have two different types of each at diferent prices, can any one tell me whats going on cuz Im a little confised and which one should I get?

Also what did you notice after you did these mods?

 

The product descriptions explain the differences between the two types...

 

well for the spacers kits the only diferance that I saw was that they are made of different materials but they serve exactly the same purpose and both work exactly th same except one can be reused many times opose to the other, am I correct?

 

Yep.

 

what about performance? any more power feel?

 

only difference is econo brand and ultra prem brand both are high quality and tested products that will outlast the car

 

One set has 5 pieces, the other 3. One set is Phenolic and can be reused over and over, the other is of a different material that is recommended for only a few applications; (meaning removing and re-installing the UIM.)

OP, you're asking vague, simplistic and open-ended questions about a product that has volumes of information. There are countless threads on Phenolic Intake Spacers. Please go read one.
