I'm guessing that if one opted to go with the Z1 Silicone Post-MAF Intake Hoses instead of the HPS Silicone Post-MAF Intake Hoses that the whp would possibly be the same. Ok at the end of the day one could possibly assume that if he/she went with both K&N Replacement Filters & HPS Silicone Post-MAF Intake Hoses (or Z1 Silicone Post-MAF Intake Hoses) that you can possibly have 11-14whp (maybe 14-16.77whp with tune)?
