I was browsing the AA catalog and came across the MSDS high flow cone air filter (catalog page 28). The ad claims that one can gain upto 10 more HP using this air filter. Is this true? Has anyone else used one of these?
BTW my engine is a 2056, stock FI with Raby's 9550 cam and tuned MPS. HPH sells a bored throttle body and claims HP gain with the TB. True?  |

Just remember with the 1.8 L-jet you have a built in flow restrictor......
A spring loaded air flap that requires air pressure to open it and to set the fuel flow... Performer enhancer it ain't, but then again it's pretty reliable- unless you have an air leak downstream from the flap.... That's why the later versions of Bosch EFI took out the flap and used a low flow restricting hot wire.... |

(IMG:style_emoticons/default/agree.gif) That's why if you really want to make HP with a the flapper style AFM(air fuel meter), the design of the tube/adapter is as important as the the air filter. You are trying to make the smoothest transition from the round intake tube to the square throat on the AFM. This is what the spec miata guys do.  |
