is it better to get cold air intake or performance headers?also has anyone bought a cold air intake, or performance headers from ebay? they're really cheap, kinda makes me think they're to good to be true. if anyone has personally bought and installed these items. how did they work?i'm shopping on ebay for this stuff because i don't have a huge budget so i'm trying to stay relatively cheap.thanks for the help!
hey bro cold air intakes and short ram intakes each give little aded horse power. if u do opt to buy one though get short ram as one of my buddies just had his engine hydrolock as his cold air intake sucked up water from a pudle a few days ago in his crx. buy the short ram intake off OKorder. im gonna tell u from experience, there is no difference in performance that u will notice between the 150 dollar injen intake vs the 35 dollar OKorder one. ive had both and there is absolutely NO diference except my wallet being happier and fuller. headers is a different situation. usually the top brand names do make a difference with headers (and cat back exhaust systems). witht he intake its simply a tube with a filter, however the build quality and longevity of the header will depend greatly on the brand. but again, even a header may only give u an additional 3 - 4 horses more power (and u wont even noticve that) i've got a dc sports header on my civic and it hardly made a difference. However in combination with the short ram intake it does give it a nice aggressive sound. OKorder stuff is fine, when u buy brand name stuff with intakes ur just supporting the companies. bottom line: for sure get the short ram over the cold air intake. as for ur header go with DC.
Im not sure a blanket will help much, the radiation of the cold should still pass through. to reduce some cold i reccomend blocking any spaces in the house that connects i outside. Example: spaces under door, windows.
yeah u can i lived in a garage for 2 years i used sheets and blankets to block out the cold spots but had a heater to help
Yes it is true that cold air is better, but there are some short ram designs that outperform cold air intakes, the reason being design. A short ram is safer unless you use a CAI with a bypass valve so you don't submerge the filter in a huge puddle and end up bending snapping a few rods. Don't expect a noticable difference in either, esspecially the headers. Your intake will be louder without a resonator but it wont sound bad if its done right, and the headers will give you a slight and I mean slight increase in midrange. I hate to sound like johnny raincloud but I have been doing this is over 10 years and that D series engine that you have isn't going to respond as much as H22 or K20 simply because it dosen't push enough air. If your looking for a few hp then I would go the intake first, then a catback exhaust and then a header. Then you could look into chipping your ecu for optimal gains and so forth. I would look into an engine swap if you want bigger gains that will be noticable, like a b16a or b18c engine, the dohc heads flow better then the d series sohc heads.
Cold Air Intake (CAI) allows colder air outside the engine bay into the engine. Where I live, I had recorded 28.83 km/l with RON 92 petrol - under ideal condition (manufacturer recommended more expensive RON 95). However, there must be air cold enough to make it works. It it is normally hot tropical air available in Singapore during most of the days. many/most end-users find this device not so practical Ram Air Intake (RAI) allows dynamic air pressure to over come the frictional loss when air is filtered before entering the engine. I experienced engine torque similar to 4th gear while driving in 5th gear with a little fuel saving, too. However, the car has got to be moving forward to make it works. Where I live, there is traffic jams almost everywhere, everyday. Many/most end-users find this device not so practical There is no off-the-shelf CAI or RAI available for my after-market Accent 1.5. So with a little research I configured my dedicated forced draft cold air system (better than supercharger or turbocharger, no moving parts). It works like CAI when cold air surrounds the non-moving car, and like RAI when I am driving the car (feels like driving a sport car version of this sedan/saloon) Looking forward to impressive fuel-saving
