Yes there are but they'll cost you more and won't be drop in like the STi's. The PE's run $750/set if you need 650 or 800 cc. Just get STi injectors. I'm not sure why people ***** about the price. Anytime you are under $150/injector you're doing great for a Japanese Denso unit. I've never seen a Denso unit for less than $100 each.PlatinumWRX said:Are there any other Nippon Denso options for fuel injectors? The STi's are a lock on the market. SUX!
