I own the PSP filter set up and was thinking about buying the 90mm mass air for my 99 lightning but am worried if the size diffrence would affectect the performance much. If so, would it really be worth buying.

thanks for any replies

 

It's worth buying! Sell your PSP setup to someone with a 99/00 MAF, & buy the 4" adapter & 1" big mouth from JDM for $115. You'll probably get that for the PSP, So what do you have to lose? It will definatly out flow the PSP, But I think that with all this 90 MAF changing going on, SAl will come up with a new setup. I sold my airaid kit to buy the JDM setup. Airaid sold for about $130, JDM's kt cost $115. See what I mean? Lloyd
