It's not about being an "EXPERT", its about common sense. Claims of 15-25 HP, by makers of air intakes on average cars of from 100- 300HP are just bullsh*t. I posted the answers to saskins and others so that people that aren't motor heads would have a chance to see information from someone with a background in high performance. If you don't at least read or research data readily available to you (on this very forum), then you really do get what you deserve. Its become a generational issue, most of us over the age of 50 take responsibility for things we do. Many of those under that age seem to feel it is someone else's job to protect you from yourselves. CAVEAT EMPTOR it's a latin phrase that is applicable here. BUYER BEWARE!!! It's a good rule of thumb to live by. BILL
